So, if I put a linux bridge in a network which has PVST packets flying around, will it pass them, or silently drop them?
Should I have STP disabled on my linux box?
(I'm particularly referring to a 6.2.19-ish kernel, before the patches of the last few days)

Ordinary, STP. The 2.6.22 kernel will have all the bits to run STP in
user mode, and there is a version of RSTP in userspace see:
git://git.kernel.org/pub/scm/linux/kernel/shemminger/git/rstp.git
The RSTP code uses the rstplib and it knows about VLAN's, but the hooks
aren't there yet. Eventually, full MSTP 802.Q seems like a good idea.
Someone had sent some patches to do PVST, but PVST seems to be Cisco
centric. and the patched version was too inflexible, so I didn't put
it in mainline.
