I have acpi working fine with home made 2.4.22. Suspend does not work since I 
didn't apply swususp patch. USB works fine, too. It seems like something 
changed in kernel code after 2.4.23 version that this specific laptop model 
doesn't like.

Could you please send me your config-2.6.1 file (if it's not too much to ask)? 
I'd like to try to compile 2.6 kernel. With debian precompiled 2.6 kernel I 
experience exactly the same problems as with >=2.4.23 ones.

Could you explain me what exactly do you mean by "read performance-states"? 
I'd be happy to have a look and let you know.
