He may well have done it right, but the kernel has a hardwired
(compiled-in) initial page table for its own code, and if that's shorter
than the kernel the kernel won't run.

The solution is to link things as modules, or to expand the initial page
table; on IA32, it's in arch/i386/kernel/head.S; search for
ENTRY(pg0). (On other platforms it is elsewhere, of course.)
