Latest BIOS version
Currently I am running version 1.01 of the BIOS. This version has some issues regarding acpi and sound!
Booting a kernel
On my version of the notebook, no kernel will boot unless given the parameter "acpi=off", which breaks all ACPI features, or and this is better "hpet=disable". This is similar to what I read about the S271 http://forum.msi.com.tw/index.php?topic=99045.msg741440 where the kernel option "nohpet" is required to boot. Both kernel parameters are the same, only difference is that the first is specific for a 32-bit kernel and the second for a 64-bit kernel.
I expect this to be fixed in next BIOS versions.
ACPI
The following ACPI features are supported in Ubuntu Dapper (2.6.15) and in Ubuntu Edgy (2.6.17): - CPU scaling - Battery status - Notebook lid - Power button - suspend: both with open source ati driver as with closed source fglrx driver (version 8.28.8) - ... The following does not work with a standard kernel: - Thermal zone: this gives a constant temperature of 75 degrees. => This was fixed on my notebook by a custom DSDT (todo ref), but that broke my CPU scaling. I am still looking into this issue.

Card reader
This was the one I feared the most not to be working before I bought it; but it works out-of-the-box. The kernel complains about not knowing this device; but the standard driver works fine:

You may experience problems.
