FreBSD install on iBook G4 (14-inch Late 2004)

[Jay K]

Trying to install FreeBSD on iBook G4 (14-inch Late 2004). Both the 9.0 RC1
and RC2 install CDs yield

Decrementer exception at %SRR0: 001000e0 %SRR1: 100003030

The 8.2 install CD fails to boot with the same message, though %SRR0 is
00100100. The 7.2 install CD boots fine as does Ubuntu LIveCD. Any hints
would be greatly appreciated.

Regards,

Jay
