sparc64 kernels have KVM problems(?)

I finally got a place to setup my ultra60 and turned it on the first time in
about a year and a half last week. I'm currently in the process of updating
it and have hit something of a bump (though I'll work around it for now). It
seems that while a GENERIC kernel works fine, my custom kernel config that
just removes unused devices from GENERIC doesn't boot. Instead it ends up
doing a panic very early on like so:
OK boot test -s
/boot/test/kernel data=0x2bfe08+0x54fa8 syms=[0x8+0x4a880+0x8+0x3f4b1]
Turning off DMA for ATA.
jumping to kernel entry at 0xc0040000.

The traceback corresponds to this (note that gdb gets the trap_pfault() frame
wrong by a few lines which is odd):
0xc00fa59c is in panic (../../../kern/kern_shutdown.c:536).
0xc024c068 is in trap_pfault (../../../sparc64/sparc64/trap.c:456).
0xc024c3d8 is in trap (../../../sparc64/sparc64/trap.c:324).
No source file for address 0xc0040ff8.
0xc02480f8 is in pmap_remove_tte (../../../sparc64/sparc64/pmap.c:1121).
0xc02488a4 is in pmap_enter (../../../sparc64/sparc64/pmap.c:1365).

0xc0040034 is at ../../../sparc64/sparc64/locore.S:86.
Anyone have any ideas? (Note that this is with a 32-bit time_t still, I'm
still in the process of doing the 64BTT update and was trying to figure this
out before going on.)
