As Patrick Boutilier pointed out ReiserFS works fine with LVM.
Basically LVM is transparent to any Filesystem/Database System etc.

ReiserFS needs special support to work on LVM snapshots though.
Chris Mason and I created a VFS extensions which even allows ReiserFS
to be mounted on LVM snapshot logical volumes.
Hopefully this patch will make it into 2.4.0.
BTW: it will be included in LVM 0.9.
It is (not yet) available for 2.2 though.

Talking about RAW device support, Stephen Tweedies raw device patch 
allows you to bind a character device to _any_ block devices
(including LVM) to provide genuine Unix raw character device semantics.

2.4.0-textX contains it.

There's a raw device support patch for 2.2.17 available at
ftp://ftp.kernel.org:/pub/linux/kernel/people/sct/raw-io/
