Sounds perfectly reasonable to me, that's pretty much what I have, though
without the shame of previously having windows on the machine :-)
PV /dev/sda7 VG vg00 lvm1 [20.00 GB / 0 free]
PV /dev/sda8 VG vg00 lvm1 [9.89 GB / 0 free]
PV /dev/sdb1 VG vg00 lvm1 [34.18 GB / 3.18 GB free]
...and yes, I swap to an LV too...
