Probably, since in a single-drive, using-all-of-it setup, LVM really  
doesn't buy you anything at all, it only adds complexity.

Should be perfectly accessible. Might require manually running some  
lvm commands and mounting by hand, not sure about that. The only real  
gotcha is that if the volume was formatted with LVM and a VG and/or LV  
with the same name as another disk in the system, things can go haywire.
