Yow! No X mouse with 2.2.17

[Wilhelm Fitzpatrick <rafial@well.com>]

I just updated by PB3400 with the latest packages from frozen, which
included a 2.2.17 kernel (The .deb says pre11, the kernel just says 2.2.17
when it boots).

GPM mouse works on consoles.  But when X comes up... THE MOUSE DOESN'T
MOVE!

I'm still running the same Xserver (Xpmac-rev9) and booting back to my
older kernel 2.2.17pre5 restores mouse function.

What's up?  Any ideas why X can't read my mouse with the new kernel?
