Which version of Debian are you using?  Etch/Sarge?  And are you using 
an SMP kernel, or just starting with one processor?  From what I have 
researched so far there seems to be needed kernel support to grow LVM's 
over hardware RAID.  Sorry to ask details instead of providing answers, 
but I think these details may affect the answer(s).
