But it has only been a couple of days.  :)

Or using 2.6.26 worked too.  Maybe 2.6.18 did something wrong.

Ehm, linux kernel detected it as a g3blue&white.  I wonder why it would
misdetect it that way.

Oh OK.  I will try updating and then redoing the install with quik.

Yeah so I noticed.  Still made me confused since the machine type
detected by the linux kernel is supposed to be newworld, but it also
detects the machine as oldworld.  So qemu bug or linux kernel bug?

OK, I will try an update and see what happens.

Oh OK.  Given the progress on ppc emulation since 0.9.1, I am sure it
won't be long before that is all working very well.
