So far, a 6.99.43 kernel works, a 6.99.45 kernel panics in the manner
described earlier.

My custom YEELOONG kernel config has a curious problem.  With all
framebuffers except "lynxfb" disabled, the kernel fails linking with:

[...]
--- netbsd_dsk ---
#      link  YEELOONG/netbsd_dsk

If I include "genfb" (normally commented out of LOONGSON config), the
kernel links, but panics at boot with "cnopen: no console device".

If I include at least one other non-genfb framebuffer ("sisfb" in
my most recent build), the kernel links without error and provides
a working console.

I'm going to build a full 6.99.43 release to update on my SD card
rootfs and then roll forward to 6.99.44 to test next.
