unfortunately (I'm the e.vacchi of the bugreport) the released updates
for the bios does not work as expected; from other reports here on
launchpad IIRC it looks like they don't addres this issue at all

I've tested one of the patches listed a few comments before the one
you're quoting; as I've answered, #127 and #128 are essentially a
pretty printed version of the one I've tried and an automated
acpi=force; I've tried to recompile 2.6.22 today (before I had only
tried 2.6.20) but looks like the new linux-source-2.6.22 on the
contrary of linux-source-2.6.20 lacks many of the drivers and it would
take for me a lot of time to figure out the whole procedure

They *are* a bandaid for a buggy bios, but the whole point in this is
"if it works in Windows, why must have linux users to be penalized?";
the whole bug report is an interesting reading in this sense

I don't think this would help; and btw I've tried 2.6.23 and it didn't
fix the issue; unfortunately this ugly patch seems the only way to
make it work; I would rather try to push the kernel devs so that this
hack can make it into upstream, so that
1) not only ubuntu but the whole community can benefit of the "bandaid"
2) ubuntu devs won't have to locally maintain the patch :)
