The subject Cyrix chip has the "coma" bug, and attempting to boot the 2.3.10 kernel with the vesafb code enabled (vga = 791 in lilo.conf) results in a frozen system immediately after the mode switch. That is, the video mode switches, but the screen goes blank and the boot process goes no further. I don't know that the system freeze is dependent on the vesafb code being enabled: I simply note that the video mode switch is the last thing seen before the freeze.
A known good workaround is to back out the 2.3.10 patch section that removes check_cyrix_coma() from linux/include/asm-i386/bugs.h.
To the faction that believes the coma workaround should be a user space thing, I submit that the fix is needed well before any userland process can get a crack at the CPU :-).
