although there is nothing like 'standard Linux quotas',
because (almost) every filesystem, either brings a bunch 
of quota routines, if not an entire quota system (like xfs) 
with it, or doesn't support quota at all (like jfs), but 
in any case the quota stuff lies somewhere between blocklevel 
and filelevel access, and I don't think that there are many 
possibilities for collisions with something like raid or
lvm/devmapper (which is basically slightly below block level).

the 'standard' filesystem is ext2 (or ext3 nowadays ;) and
the ext2/ext3 quota had some issues for a while, mainly
because it is fairly complex and not widely used. AFAIK
none of those issues where ever related to lvm or md.

to answer your question, yes ext2/ext3 quota and the
journaled quota xfs provides do work on lvm (over raid5)
(at least for me ;)
