What PROM revision do you have?

The rev 7.0 PROMs reported cannot boot kernels with text+data+bss
greater than 1 Mbyte (the PROM allocates a page of data at 1Mbyte,
trashing the kernel that it's loading.)

I have a rev 7.01 which have both netbooted recent NetBSD/pmax ECOFF
kernels via Ethernet just fine, as does a 7.02 PROM.

All my ms01 SIMMS are all in a 5000/150 right now or I'd verify that
the rev 7.01 KN01 still boots the kernel on the FTP site.
