My original post requested a list of manufacturers and corresponding
MAC address prefixes. A summary of the responses follows:

From: Larry Brigman <motbos!decwrl!riacs!rutgers!fai.com!lbrigman@mcdhup>

There is a list of some manufactures in the rfc's
The number of the rfc that has that is 1060.

From: Doug McCallum <motbos!decwrl!riacs!rutgers!central.sun.com!Doug.McCallum@mcdhup>

There isn't a way to get a complete, up-to-date, list.  This is
considered proprietary by IEEE since there may be vendors with an yet
unannounced products.  The best you can do is find an incomplete list.
There used to be a list on ftp.lcs.mit.edu in pub/map/EtherNet-codes.

From: heisen@convex.rz.uni-duesseldorf.de (Henner Eisen)

rfc1340, which can be ftp'ed from many servers, contains a list of
several ethernet vendor address components. I don't think that it is
complete but all major manufacturers seem to be included.

From: seifert@netcom.com (Rich Seifert)

Vendors who have received address blocks from IEEE/ISO have been 
guaranteed anonymity up to this time. There is no "official" list of
who has which assignments, or even who has an assignment at all. There
is a general desire on the part of users and network administrators to
get such a list. The IEEE has sent a letter to every address block
owner asking if they are willing to have their name and block assignment
made public. There should be a list forthcoming (a few months in the future)
of those vendors that respond affirmatively. In the future, address
blocks will be public knowledge unless a vendor wishes and requests
anonymity.

This was discussed in detail at the IEEE 802 meeting earlier this
week in San Diego.

For an unofficial and incomplete list you can look at the latest
Assigned Numbers RFC, available from your friendly neighbourhood
anonymous ftp site.  RFC 1340 (dated July 1992) contains a list of 106
MAC address/vendor pairs.

My thanks to everyone who responded. I was able to get the file
pub/map/EtherNet-codes suggested by Doug McCallum. It had been updated
the day before I retrieved it (11 Nov) and was quite comprehensive. 
A "because I *can*" comparison against the various cards we had lying 
around the shop (I work for a VAR/Systems Integrator) showed the list
to be accurate also. 

Again, my thanks to the netfolk (or in Henner's case NetVolk) (Bitte
trinken Sie einen Altbier fur Mich, Henner!) and I hope this summary 
will help someone else out as well.
