Did you try 2.6.18-rc6 from : http://kernel-archive.buildserver.net/debian-kernel/trunk

Which contains a workaround for the bootx bug ?

Indeed, maybe you could try the miboot-on-a-disk solution Aurelien proposed
you ?

The problem is that for some obscure reason, the ramdisk is not read, and thus
the modules placed there by the ramdisk generator not loaded. This is the bug,
and building-in this module will pave the way to go back to the bloated 2.4
kernels we used to have, with world+dog builtin.
