The ACPI warnings might be harmless, but there's nothing obvious I see 
outside of ACPI that might be related to your problem (ACPI maintainers 
Cc'ed).

Try CONFIG_USB=n

CONFIG_USB_SUSPEND=n is most likely enough.

That's an unfixed 2.6.20-rc regression reported more than once, the 
first time in December last year...

Hi!

CONFIG_USB_SUSPEND=n does the job. But the patch from
http://bugzilla.kernel.org/show_bug.cgi?id=7828#c29 works for my system
too (with CONFIG_USB_SUSPEND=y). The bugreport was made for an ACER
Travelmate 4001 WMLi, which is almost identical to my Acer Extensa 3002
WLMi.
