I've tried this on a Performa 6400/180 (603e), and also got a panic right after Meta-G.

>From manual work on the backtrace, the following functions are accessed:

c0044c7c: c0044c04 t insert_pte
c004498c: c004485c t page_fault
c004478c: c0044704 t mmu_data_access_hook
c0041d80: c0041d78 t access_exception

This is a cvs-kernel, but not the one from the mac-on-linux-site, 
but the patches applied cleanly.
