	In case it helps you to know this, I'm looking into a similar
problem in 2.5.57-58 which may be related to what you (Felix) are
reporting.

	For some reason that I haven't figured out, USB keyboard and
mouse that are recognized in 2.5.56 are not recognized by 2.5.57 or
2.5.58, even though lsusb sees them.  This is the case on the two
different systems that I tried (with a different keyboard and
a different mouse).

	There were no changes to drivers/acpi between 2.5.56 and
2.5.57, and booting with acpi=off does not eliminate this problem.
There were few changes to usb between 2.5.56 and 2.5.57.  So, I
suspect that USB no longer working is a side-effect of some other
change.
