Checking back, the last mmotm to boot successfully on this platform was the 25jun09 snapshot. The offending patch appears to be commit 0b8d7a6fbba81ffd06de701fa6178916ee9732c3 - "serial-add-irqflags-support" in the linux-next mega-patch. Reverting the changes to the 8250 driver allows the kernel to boot and operate normally.
