Problems booting Wheezy/sid kernels on ps3

[David Mattli <dmm@mattli.us>]

Has anyone had success booting a Wheezy or Sid kernel on a ps3? For me
it's freezing immediately after petitboot on a blank screen with a
single(unchanging, no blinking) "_" in the UL corner. The
2.6.32-5-powerpc64 kernel works fine.

Specifically linux-image-3.0.0-2-powerpc64 and
linux-image-3.0.0-1-powerpc64 are not working for me.

Thanks,
