The number 28672 is the size wired into the Kernel to tell it
how big the swap partition is - since 34068 > 28672 you aren't
running off the end (the SCSI driver prevents you from doing
that anyway, so swap isn't the reason why you are trashing your
Mac partition).
The size of swap is set using kconfig on /unix (and /newunix if
you want it to persist across autoconfiguration) - check the
manual page for details. This little irritation is fixed in
A/UX 2.0 where the kernel manages to read the partition map to
find out the size of swap...
It would be helpful to see the complete output of dp, and the
output of kconfig -va /unix; I'll read the entrails if you care
to mail them to me (summary of answers to the net of course).
