The PCI-SIG provides specs free to its member companies and charges for 
physical copies (the membership fees for the PCI-SIG are substantially less 
than for the IBTA and there are other benefits of membership beyond free 
specs).  There are special discounts in place for academic purposes.  Given 
there are over 900 companies in the PCI-SIG and I suspect a large 
percentage of the people on this reflector work for member companies, you 
should have free access to the specs (Grant has full access via an internal 
website I manage for distribution of such material within HP).  I would 
also note that the latest specs are:

PCI 3.0 for conventional PCI
PCI-X 2.0a for PCI-X
PCIe 1.0a for PCI Express (will soon be 1.1 which incorporates nearly all 
of the ECN / errata generated over the past year as well as the corrected 
error handling that will be important for people to understand since the 
1.0a spec is broken in this regard - a final ECN for 1.0a should also 
become available shortly).

BTW, MSI-X was technology originally conceived within HP many years ago 
(~15) and developed within the PCI-SIG as an extension to MSI a couple of 
years ago (I first proposed it during the development of PCI Express and we 
decided to make it applicable to all PCI technologies - ECN exist for all 
three types).
