nope, you cant' change the partition type and you don't need to,
the problem lies somewhere else.
lvm1 is very picky (serverely broken) about device file names,
do a lvmdiskscan and or cat /proc/partitions and check which device name
you find.
if you have devfs compiled in the kernel and not mounted lvm user tools
will NOT work.

i cc-ed lvm list which is a better place to ask elp on lvm...
