We have the same situation with the dreamplug (kirkwood based).

I'm attempting to, but that requires my learning devicetree. Which is
fine in and of itself, but it also means I'm learning how Linux supports
arm SoCs. Which is taking some time. My current thought process is this:
1.) add arch/arm/mach-kirkwood/board-dt.c, arch/arm/boot/dts/kirkwood.dtsi,
and arch/arm/boot/dts/kirkwood-dreamplug.dts
2.) fill it in with replacements of calls in common.c and irq.c
3.) get it working cleanly.
4.) add in calls from mpp.c, pcie.c, and cpuidle.c
5.) build arch/arm/boot/dts/kirkwood-*.dts for other boards.
I'd be happy to coordinate and test, although I have no buffalo gear.
And I sure would appreciate some help. ;-)
thx,
Jason.

Resend, messed up my email alias. I'm a dork. :-( Apologies.
