Interesting: I just had a similar experience with the 2.4.7 kernel
I built for my laptop yesterday. It worked fine for the first few
boots.  But after a while, upon starting X, at the end of the
kde2 initialization the machine froze and I had to pull the battery
out to reset it (then reboot and fsck-repair all the disk damage).
This has been repeatable and I have no idea what's wrong.
Vaio SR17k, Redhat 7.1.  Redhat's shipped kernel (2.4.2-2)
works fine, as does a 2.4.2 I downloaded and built with the same
.config as I used for the 2.4.7 kernel (couldn't build from Redhat's
2.4.2 source tree, syntax error in module.h).

Is there an archive of that thread?  I have a network card and 
another machine.

I haven't actually tried telnetting in from another machine.
I've tried ctrl-alt-Fn to get to other screens, and c-a-backspace
and c-a-delete, and got no response.

I'm not knowingly running xmms, but who knows what-all kde2 is
running for me behind the scenes (I had to turn off sound because
it does something funny to my sound card when it starts up and I
get a loud buzzing that won't go away until I power off). 
Hmm, maybe I should try gnome and see if the kernel works there.

Those aren't what I'm seeing, since the keyboard still works in
both reports.
