Mkfs and the code I found in the Kernel both determine partition types by 
the contents of the partition name field, so there does appear to be a 
mismatch here. Sorry, but I never dug very deep into the Installer code 
to find out how it determined partition types.  I had been told a couple 
of times about these bit definitions, but I never found them in my old 
version of CodeWarrior and didn't bother reloading an even older version 
of Think C.  I'll dig into mkfs and see if I can straighten this out.  
The original mkfs never looked a the pmPad field in the Partition Map 
entry, and I never changed that.  It would appear that this needs to be 
added to mkfs and possibly to the Kernel as well.  I'll make the changes 
to mkfs tonite.  If Steve is willing to test them maybe we can have an 
updated mkfs available in a few days.
