Trouble with newer kernels on Gumstix Overo boards

Hi Tony et al,
I'm having problems booting newer kernels on a Gumstix Overo board.
I enabled CONFIG_EARLY_PRINTK to see any messages at all, and see a
number of warnings first and then lots of garbled binary junk once the
UART is set up.
This is Linus' current master branch plus your latest fixes from
git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git fixes
Uncompressing Linux... done, booting the kernel.

... and lots of binary junk after this line. Seems like the UART is
configured to some other baud rate at this point, but I can't see the
reason yet. Most probably, the kernel runs into an Ooops later on
which I can't see as my serial console is toast.
Older kernels (ie, 2.6.36) work just fine. Do I miss anything obvious?
Thanks,
Daniel
