Ultra10 problems with -current

[Sad Clouds <cryintothebluesky%googlemail.com@localhost>]

Trying out -current on Ultra10, however kernel simply hangs when trying
to load from install CD, the last lines printed are:

...
machfb0: initializing the DSP
machfb0: initial resolution 1152x864 at 8 bpp
machbf0: attached to /dev/fb0
post div: 2 log2_post_div: 1 mclk_div: 228
vclk_ctl: 03
machfb0: initializing the DSP

Any ideas?
