I'm seeing the same problem with 2.6.17-rc1 on my Powerbook6,8.  I
get a little further by passing "video=ofonly", which allows me to see
these messages:
[ 27.559054] initcall at 0xc02db560:TAU_init  +0x01 0x104(): returned with error code 1
[ 27.560507] initcall at 0xc02ec38c: init_autofs4_fs +0x010x28(): returned with error code  -16
The last line I see is 
[ 27.642195] sungem.c:v0.98 
Disabling  CONFIG_TAU makes the  first  message go 
away,  but  the  second  one  is 
still  there.
