I was exited then as someone has reported a problem with GPLPV where the
rx path appears to hang (due to running out of resources) after some
days, but unfortunately it's with 2003 not 2008, and it looks like it's
packets that it's running out of, not buffers. D'oh.

That kind of removes the attraction a bit. It sounds like 5.2 is a bit
of an orphan as it isn't mentioned anywhere but the SNP KB pages (in
overview form), and most of the links from there have suffered some
major bitrot and either redirect to NDIS6.2 or to 'page not found'.
