Sorry for the delay in answering, I've been busy with Work,
and with debugging serial consoles.
* /dev/pm0 does nothing. NetBSD/pmax uses a hardware-independent
pseudo-device to access framebuffer hardware. Create /dev/fb0 and
make a symlink from /dev/fb and /dev/mouse to there.
I rebuilt a new base.tar.gz with a fixed MAKEDEV yesterday; if you can
wait about 2 hours, that will be on ftp.netbsd.org and
* I beleive that procfs works; the GDB hooks for NetBSD/pmax use it.
(ptrace emulation would be neat, but no-one has had time.)
Re SysV IPC:
* I have never tried System V IPC, there may well be un-initialized
variable that need to be set up for SYSVIPC. If you have time, check
the Pica port for sysV initialization.
* No, they don't work. All the machinery is in place except in the
driver. This is waiting for the MI scsi drivers to be dropped in.
