Hm, seems that it entered mainline post 2.6.32 (early December 2009 ...) so
unfortunately it's not in the bpo Kernel and currently won't be part of
Squeeze.
I don't know how much work it is to backport the driver to 2.6.32 but
you might want to try to open a wishlist bug against linux-2.6 and
ask for the inclusion of the driver.

So you've at least two choices now for Lenny which should work without too
much hassle:
a) Grab the 2.6.35 source package from experimental and rebuild it on
Lenny.
b) Use make-kpkg to build your own Kernel image.


Regarding the hardware I don't have experience with the G5 servers nor with
the new driver but a working (and charged) BBWC could do some smaller wonders
in the past. Bottleneck analysis is hard sometimes though and highly depends
on the workload, disk setup (RAID? Which level?) and filesystems (noatime?).
