You can just install a 64-bit kernel. For rpm based systems you have to
"unpack" the rpm using rpm2cpio. The modules.dep file cannot be updated
-- need to generate that elsewhere -- and mkinitrd needs to be modified
to not try to strip modules (s,strip,true,).
That's all I had to do to plop a 64-bit kernel onto a 32-bit install.
