Once again tried it both on an NC and an A7000 (12MB).

On the A7000 with the A7000 kernel, it manages to get into kernel, but the
kernel panics with "Video DRAM is being unpredictable". 

On the NC it doesn't get that far. The error "No DRAM maped in this
program (wierd) (sic) ... Increase Wimpslot?". Tried increasing the
Wimpslot as high as 8MB; still no joy.

Reported messages:

Used 1st Mb of DRAM at 0x10000000 for video memory
Found DRAM (0) at 0x10100000 for     15360 k
Found DRAM (1) at 0x14000000 for     16384 k
Found VRAM (0) at 0x00000000 for         0 k

Found memory blocks 0x100AD000-0x100F3000  0x100FB000-0x1073F000


Also, !Boot still refers to BtRiscBSD$Dir and the *RMKill UnixFS line
should be wrapped in SYS "XOS_ClI" in case UnixFS is not being used.
