CONFIG_DEBUG_INFO is the basic switch. I don't know if MIPS needs
CONFIG_FRAME_POINTER but that could help too.
I don't see CONFIG_FRAME_POINTER available.
I compiled with CONFIG_DEBUG_INFO; let me know if I should enable some
other DEBUG options as well (see below what's enabled and available).
Before it oopses, I see lots of order 0 page allocation failures (there
are some extra spaces at the end of each line due to the broken konsole
in KDE4):

Once, the device hanged without producing an oops (with lots of page
allocation failures before).
No clue about disassembling here, sorry.

Another option in the absence of debug info is disassembling the
Code: section of the oops and trying to find the corresponding
code via objdump, but this only really works well if you have some
idea which module is causing the error.
