kernel 2.6.2-1.81 problems

[Neal D. Becker]

I just tried kernel 2.6.2-1.81 on my FC2 system.  There are a number of new
problems that were not there on 2.6.1-1.65.

0) *** This system was already updated to FC2T1 and was 100% working,
including alsa***

1) modprobe complains about keydev (fatal) and mousedev (fatal).  Messages
not logged by syslog, so I can't post them.  Strangely, mouse and keyboard
are working anyway.

2) alsa sound is not working.  At boot there are a bunch of alsa-related
error messages:

3) This looks bad:
