Well, what I'll probably do is wait until the X server people at Metrolink
are done testing my i386 laptop (don't get your hopes up, it's running BSD/OS
right now), then use it to try to build -current, and once I have a buildable
-current, I'll try it on my alpha.  :)

Thanks for the tip, I'll give it a try.
