I've subsequently found that adding a call to wsfont_init() before
wsfont_find() in smg.c fixes the missing font. With a serial console, I
now see:

smg0 at vsbus0 csr 0x200f0000 vec 104 ipl 17 maskbit 3
wsdisplay0 at smg0 kbdmux 1

However, it still hangs with a blank screen if I boot with the
framebuffer console. If I enable wscons in rc.conf, and boot with the
serial console, then I do get a login prompt on the frambuffer and I
can login and run commands. But if I switch to another virtual
terminal then the kernel double panics:

panic: Segv in kernel mode: pc 8003a281 addr 7f67ad8a
Begin traceback...
panic: Segv in kernel mode: pc %x addr %x
Stack traceback :
         Process is executing in user space.
End traceback...

Should I send-pr this?
