>Description:
	Typing the "fn" key along with the up-arrow key on the new
iBook, in an attempt to move up a page, triggers an odd panic:

trap: kernel ISI by 0x55555554 (SRR1 0x40009032)
Stopped at 0x55555554:

Although DDB is compiled into the kernel, it doesn't get there.

The same basic problem is present in 1.5.1, although the trap message is
less verbose, and the DDB behavior is different (the kernel
successfully drops into DDB, but I can't type at it).

>How-To-Repeat:
	Press fn-up (pageup) on a dual USB iBook.
>Fix:
	Unknown.
