 	  This driver provides support for the IBM Hard Drive Active Protection
 	  System (hdaps), which provides an accelerometer and other misc. data.
-	  Supported laptops include the IBM ThinkPad T41, T42, T43, and R51.
-	  The accelerometer data is readable via sysfs.
+	  ThinkPads starting with the R50, T41, and X40 are supported.  The
+	  accelerometer data is readable via sysfs.
 
-	  This driver also provides an input class device, allowing the
-	  laptop to act as a pinball machine-esque mouse.  This is off by
-	  default but enabled via sysfs or the module parameter "mousedev".
+	  This driver also provides an absolute input class device, allowing
+	  the laptop to act as a pinball machine-esque joystick.
 
 	  Say Y here if you have an applicable laptop and want to experience
 	  the awesome power of hdaps.

- *   --BenH.
+ *  - maybe add timeout to commands ?
+ *  - blocking version of time functions
+ *  - polling version of i2c commands (including timer that works with
+ *    interrutps off)
+ *  - maybe avoid some data copies with i2c by directly using the smu cmd

+ *
+ * This driver uses the sungem driver (c) David Miller
+ * (davem@redhat.com) as its basis.
+ *
+ * The cassini chip has a number of features that distinguish it from
+ * the gem chip:
+ *  4 transmit descriptor rings that are used for either QoS (VLAN) or
+ *      load balancing (non-VLAN mode)
+ *  batching of multiple packets
+ *  multiple CPU dispatching
+ *  page-based RX descriptor engine with separate completion rings
+ *  Gigabit support (GMII and PCS interface)
+ *  MIF link up/down detection works
+ *
+ * RX is handled by page sized buffers that are attached as fragments to
+ * the skb. here's what's done:
+ *  -- driver allocates pages at a time and keeps reference counts
+ *     on them.
+ *  -- the upper protocol layers assume that the header is in the skb
+ *     itself. as a result, cassini will copy a small amount (64 bytes)
+ *     to make them happy.
+ *  -- driver appends the rest of the data pages as frags to skbuffs
+ *     and increments the reference count
+ *  -- on page reclamation, the driver swaps the page with a spare page.
+ *     if that page is still in use, it frees its reference to that page,
+ *     and allocates a new page for use. otherwise, it just recycles the
+ *     the page. 
+ *
+ * NOTE: cassini can parse the header. however, it's not worth it
+ *       as long as the network stack requires a header copy.
+ *
+ * TX has 4 queues. currently these queues are used in a round-robin
+ * fashion for load balancing. They can also be used for QoS. for that
+ * to work, however, QoS information needs to be exposed down to the driver
+ * level so that subqueues get targetted to particular transmit rings.
+ * alternatively, the queues can be configured via use of the all-purpose
+ * ioctl.
+ *
+ * RX DATA: the rx completion ring has all the info, but the rx desc
+ * ring has all of the data. RX can conceivably come in under multiple
+ * interrupts, but the INT# assignment needs to be set up properly by
+ * the BIOS and conveyed to the driver. PCI BIOSes don't know how to do
+ * that. also, the two descriptor rings are designed to distinguish between
+ * encrypted and non-encrypted packets, but we use them for buffering 
+ * instead.
+ *
+ * by default, the selective clear mask is set up to process rx packets.

+  2005-09-20  v0.4.4 increased recv buffer size: the card sometimes
+                     wants to send >2000 bytes.
