Log Message:
Support UDMA66 on Asus Eee. (experimental)

linux-2.6-sata-eeepc-faster.patch:

--- NEW FILE linux-2.6-sata-eeepc-faster.patch ---
The Asus Eee PC prints this during bootup..

ata2.00: limited to UDMA/33 due to 40-wire cable
Which is unfortunate, as it has..
ata2.00: ATA-4: SILICONMOTION SM223AC, , max UDMA/66

I believe there actually is no cable, and the flash is directly
connected to the controller.

[root at eee ~]# hdparm -t /dev/sda

/dev/sda:
 Timing buffered disk reads:   64 MB in  3.08 seconds =  20.76 MB/sec

With the patch below it returns..

TBD
