my problem using iBook G4

[Weongyo Jeong]

Hello,

I have a iBook G4 laptop but it has a problem when booting like as
follows:

My booting steps are:

	1. press <option>+<apple>+O+F
	2. 0 > boot cd:,\boot\loader hd:7
	3. then a panic during booting progress

There's no problem to boot if I set `OK set hw.ata.atapi_dma=0'. Is it a
known issue?

I'd like to print a backtrace of DDB but no ways because the keyboard
(normally it works perfectly after successful booting) didn't worked.
Moreover the USB keyboard also didn't worked.  Are there any methods in
this case?  (I'd also like to get a coredump file for kgdb)

The kernel and world updated yesterday.

regards,
