Right now the DOS plugin doesn't provide a way to change partition-types. 
We've never added this function because, in general, it's never necessary on 
Linux systems. Partition-types are simply a left-over from old DOS and 
Windows systems. And it's possible that early versions of some Linux tools 
(mkfs and mkswap) looked at the partition-type before running. But this isn't 
the case any more. There's no reason that a partition must be type 0x82 to be 
swap, or type 0x8e to be used in an LVM container. So EVMS and other Linux 
partitioning tools will create new partitions with the default 0x83 type, and 
there's really no need to ever change it.

If you really, really want to change the types, you can use fdisk, and the 
next time you run EVMS, it will notice the change (although EVMS doesn't use 
the partition-type for anything).

After talking with Steve, we don't think the CLI recognizes hexidecimal input 
numbers. Sorry. :(

But like I said above, there's really no reason or advantage to changing the 
default partition-type when you create a new EVMS segment.
