Yeah, basically the 2.2 kernels don't support the needed mmap semantics.
As the openssh guys put it, loss of compression more than makes up for
the loss of a root exploit.  :)

I guess I could update the RH 6.2 rpms to have compression off by
default.. but all of my RH62 boxen are using 2.4 kernels.. so I didn't
bother.
