    I have done some more digging, including the same kernel on a second host.
    The second box has a K6, VIA MVP3 chipset, and a G200 with 8M, otherwise
    the software versions are the same. It works fine. Taking the .config
    used for that, I redid the kernel on the AthlonXP / VIA KT266a / G400,
    almost instant reboot.


    One of the crashes was a touch later, and the last few lines from
    /var/log/messages was:
    Aug 21 20:46:32 localhost login(pam_unix)[1063]: session opened for user alland by LOGIN(uid=0)

    Aug 21 20:57:29 localhost syslogd 1.4.1: restart.

    The "char-major-226" corresponds to the /dev/dri/card0 above, and the failure point
    seems to be when the drmOpenDevice succeeds on the third attempt.

    I tried unsetting CONFIG_DRM, but it still fails.
