I have an IP module driver that sets the slot memory base
to 0x7200000 on an MVME-162 (Petra). We are upgrading from
vxWorks 5.1.1 to vxWorks 5.5 (T2.2) and attempts to access
this address now result in an access violation.

I've checked the target/mv162/config.h files - the treatment
of memory seems the same. Suggestions?

Have a look at your old target/mv162/sysLib.c file, in particular the sysPhysMemDesc[] array, which defines the areas of virtual memory that get mapped to physical memory - if an address is not covered here, the MMU will reject it immediately. You probably have an entry in the old table for the IP memory base address which you need to copy into the new version.
