I just started hacking my iBook G4, and no, booting NetBSD isn't a problem at all.

I had to make a recent -current kernel because 1.6 doesn't properly support the iBook's keyboard, 2.99.10 works just fine but it has some other, pretty annoying issues.
So, several things:
- the kauai/wdc driver seems to have problems - it doesn't see my harddisk and refuses to use any UDMA mode on my CDROM, it's stuck in PIO4/DMA2. The disk is definitely ok since I load my kernel from it ( boot pci2/ata-6/disk:,\ofwboot.xcf ) - not to talk about MacOS X happily booting from it.
- I found out why XFree leaves a fscked up console on G4s - simply because UniNorth doesn't seem to map IO space into memory as it's supposed to do ( and bandit does ). So vgahw can't store any video state, let alone write it back.
- USB is weird - my Logitech trackball works just fine but a harddisk doesn't - it does however work on the S900 with an ALi USB2 controller ( in OHCI mode because EHCI still locks up ).
