For this one I can confirm that the blacklist is not needed with latest
kernel and the BIOS I use.
Beside the fact that this machine did not boot correctly due to wrongly
set up SCI irq since 2.6.31 (fixed via stable kernels now), the blacklist does
not match for my machine at all as only "System Information" and not the
"Base Board Information" used in the blacklist is filled in BIOS DMI data:
System Information
Manufacturer: IBM
Product Name: eserver xSeries 330 -[867411X]-
Base Board Information
Manufacturer: IBM
Product Name: Not Specified
I did not test whether the BIOS is up to date, though (and won't update, sorry):
Release Date: 09/20/2002
I'd also vote to remove the blacklist for ACPI test
(does this branch get synced into linux-next)?
