I am currently booting with "hpux /stand/vmunix".

This doesn't use the boot code in ipl_c.c.  Maybe the problem is the failure
in main to open "/dev/console".  Possibly, "/dev/console" is not in the ram
disk or, if it is, the kernel is not figuring out which tty to use.

I tried this and it didn't work.  It looks like __delay() is broken.  The
".balignl" is clearly bogus.  I think the "addib" tests need to bew looked
at more closely.
