I can confirm this in Intrepid, I've opened a new bug:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/285595

Perhaps it is better to signal here that the situation is not improved.

Bug description:
I have an Asus Eee PC 4GB laptop, and I am testing Ubuntu Hardy 8.04 (kernel 2.6.24-8) on it.

The computer has a 4GB SSD soldered to the motherboard. The disk is reported as UDMA66 capable, but is installed as UDMA33 because the system does not detect a 80 pin conductor.

I have tried adding kernel parameters (ide0=ata66 ide1=ata66) but these seems to be ignored. I have read that these parameters are just to instruct the kernel not to do the 40/80 wire test.

I have written a blog entry [http://ospatia.blogspot.com/2008/02/eee-pc-optimizar-el-disco-ssd.html] (in Spanish) with additional information (dmesg output, some tests with hdparm, ...) and I have found additioal people having same problem with fast (300x) Compact Flash cards.

dmesg output extract:

[   26.700245] ata2.00: ATA-4: SILICONMOTION SM223AC, , max UDMA/66
[   26.700256] ata2.00: 7815024 sectors, multi 0: LBA
