You need Roman Zippel's patch to the TT hwclock driver in order to avoid
scheduling (msleep) inside the clock setting routine during boot. It's in
CVS since at least Sep. 7.

You'll probably need his other CVS patches as well (discontig memory
support for instance).

I tested it on aranym and saw the characteristic panic message :-)

I've found a couple of bugs in my atafb patch that did result in always
selecting 4 bit depth, and consequently optimized the 8 bitplanes code
based on wrong assumptions. Shame on me. Ignore the patch please :-(

New patch will follow soon.
