after some further narrowing of kernel config, it appears that
'CONFIG_RELOCATABLE=y' is causing the kernel to become unbootable with
maverick's 32bit toolchain. unsetting this parameter produces a bootable
kernel on maverick. again, lucid toolchain produces bootable kernels
with or without 'CONFIG_RELOCATABLE=y'.

so this is what's causing it in the kernel config. according to LKDDB,
this parameter does:

'The kernel is linked as a position-independent executable (PIE) and
contains dynamic relocations which are processed early in the bootup
process.'

i'm able to reproduce this consistently now, by toggling
CONFIG_RELOCATABLE on and off in kernel compiles.

thanks,
