I don't have a 2.2.19 tree handy, but I'd guess __muldi3 needs to be
exported from the kernel for use in modules, via an entry in
arch/m68k/kernel/m68k_ksyms.c
Probably __muldi3 is only used in nfs[d].o so doesn't get linked in
to the kernel if they are built as modules.  Probably add

asmlinkage long long __muldi3 (long long, long long);
EXPORT_SYMBOL_NOVERS(__muldi3);

which is what is in the 2.4.x tree.
