According to what people reported, MIPS1-only kernel may be stable
enough to build kernels, but shows TLB miss panic when 'make install'
on /usr/src or /usr/src/lib/libc.  One of my Japanese friend told me
mdsetimage brought a similar panic.  TLB miss seems to occur
long-living processes like xntpd, which implies something wrong
happens on swapped-out (??) processes.

I suspend sfb.c/sfbplus.c effort, and take care of this issue.
