Hi alpha folks--

With the recent ia64 progress, I'm trying to figure out how to best 
support more than two architectures in the release documentation.  The 
biggest headache is going to be the hardware notes...specifically the 
lists of all the NICs, disk controllers, and other devices.

One thing I'd like to do is to figure out what to do with all of the 
devices for which no explicitly-supported architecture(s) are listed.  
In other words, does:

	<para>foobar device (&man.foo.4; driver)</para>

really mean:

	<para arch="i386,alpha">foobar device (&man.foo.4; driver)</para>

("it works on both the i386 and alpha") or does it really mean:

	<para arch="i386">foobar device (&man.foo.4; driver)</para>
	
("it works on the i386, no one's tried it on the alpha")?

I'm not sure how to go about doing this, given that the only alpha 
machine I can even login to is beast.  One thing I thought of was to
make a pass through the GENERIC kernel configuration on a FreeBSD/alpha
machine and mark all drivers mentioned there as being explicitly
supported, then taking everything that's left and marking it as
i386-only.

Clearly this isn't perfect.  Any ideas on how I can do this better?

Thanks!

Bruce.

PS.  Right now I'm mostly concerned with -CURRENT...4-STABLE will 
never have more than 2 architectures, so it's less of a problem 
although anything that's MFC-able, should be.
