Ubuntu 10.10 64-bit, Tyan Thunder S2915-E & Crucial CT256M225 256GB SSD

[allbread]

I am attempting to install Ubuntu 10.10 (64-bit) on a Crucial 256GB SSD. Currently I have a working install of Ubuntu running on the board off of a spare Hitachi 250GB drive however I ultimately want my primary boot partition on the SSD for performance reasons.

Tyan Thunder S2915-E
2 x Opteron 2378 / 32GB DDR667-RE
EVGA GeForce 275 GTX / Tuniq 1000W PSU
Crucial 256GB M225 SSD (boot)
ARC-1120 PCI-X / 3 x 2TB Hitachi 7200 RAID5 (data)

I am having persistent issues getting Ubuntu to recognize (correctly) the Crucial 256GB SSD. Although the SSD is recognized in the BIOS the Ubuntu installer fails to register it as a viable partition on it's first pass. If I reflash the BIOS of the SSD (using the "reflash" switch on front) the drive is now recognized as a 256.1 GB partition (which I think is erroneous, it should be more along the lines of 238 GB).

I have found advice online stating that the SATA controller must be set to AHCI mode however I cannot find any corresponding setting in the BIOS.

How do I go about installing Ubuntu 10.10 on a CT256M225 SSD?

I've found a thread that seems to indicate that this might be due to a bug:

...but I'm having some trouble implementing an immediate solution from the details of the thread - at least, I don't really know how to pass the kernel boot parameters described in the thread, if indeed this is the workaround the author is suggesting.

Anyone have any advice for me?

Here is something on boot parameters:

It is written for a live CD, but most applies to a regular installation as well.
