  Indeed, it does.  Last night I had the box locked (monolithic kernel 
cross-compiled and put onto ubuntu 'server' install, static ip 
brought up with ifconfig), ok until I keyed <ESC><:> in vim at which 
point it slowly flooded the screen with ':' characters and was no longer 
responding to pings.  That was repeatable.

  Today, recompiled the kernel without sound and it was up for over an 
hour on the same ubuntu system, no problems.  Now, I've applied this 
kernel to fedora and it looks good (up for 30 minutes so far, dhcp 
worked, replying via ssh to my server).

  So, very usable without sound.  I'll make yet another install of 
something I'm more comfortable with (cross-LFS, with latest udev) in a 
day or two, then I can play with the post-2.6.14 changes (fans, 
cpufreq).  Thanks again.
