I just committed a change to HEAD to add a new flag to pciconf to dump VPD 
data.  If you just need it in a shell script then 'pciconf -lV <device>' might 
be sufficient for you.  If you want it programmatically, you can use the new 
ioctl I added to retrieve it from the kernel.

If you need to do this on an older OS version where you can't backport my 
change (or upgrade to a version with this change), then you can use direct 
config register access to find the VPD capability and read the data directly 
using the VPD registers.
