ok, here's the result of testing all this with 2.5.67-bk2. i built
a new kernel and modules, rebooted and:
1) with USB optical mouse and PS/2 keyboard:
system hangs after "Freeing unused kernel memory"
2) with USB optical mouse only:
same problem as 1)
3) with PS/2 keyboard only:
boots fine, both keyboards work, and onboard touchpad works
so having the mouse plugged into the USB port seems to be the issue.
and checking further, i find that i've apparently no USB support
loaded whatsoever. i plugged in the mouse, and got no reaction
(i was tailing /var/log/messages at the time). plugged in a
USB zip drive, still no reaction at all.
/var/log/dmesg shows nothing related to USB recognition.
and another oddity is that, as the system was booting, i got
a complaint that it couldn't mount the FAT partition as the
kernel had no vfat support.
but i have vfat support as a module, however, "lsmod" shows
a really skimpy set of loaded modules. it looks like autoloading
of modules just isn't happening. i don't even have a module for
the USB bus, which explains a lot.
i have full module support selected in kernel configuration,
but it seems that the required modules just aren't being loaded
i just tested and "modprobe" seems to work, but i don't
understand why none of this stuff is being loaded at boot
i'm still running under the new kernel, so i'm willing to
entertain things i can check, but i have no X session (nvidia,
which i haven't even *tried* to set up under 2.5.67).
