Right now I mainly use it to debug a driver, which would run out of host
ram when I reloaded it

This is because I did my patch against 2.6.5, and all the EXPORT sympols
are in arch/ppc/kernel/ppc_ksyms.c
and not in commprocs.c

In ppc_ksyms.c I have:
extern uint m8260_cpm_dpalloc(uint size, uint align);
extern uint m8260_cpm_hostalloc(uint size, uint align);
extern uint m8260_cpm_hostfree(uint ptr);
extern uint m8260_cpm_dpfree(uint ptr);

EXPORT_SYMBOL(m8260_cpm_dpalloc);
EXPORT_SYMBOL(m8260_cpm_hostalloc);
EXPORT_SYMBOL(m8260_cpm_dpfree);
EXPORT_SYMBOL(m8260_cpm_hostfree);
