Hm. How old is the kernel that does work?
Could it possibly be a timing glitch in the mouse initialization??
Somehow that seems more likely than that the cursor-initialization
changes are stopping the serial port from sending data.
And it's the same serial chip as the keyboard, so changes in the
attach code dont seem a likely culprit.
