What architectures does DragonFly support?

DragonFly is currently targeted at the x86 line of processors; it should
work on 386 and up, though a 386 is certainly not recommended.  Work is
also being done on support for the new 64-bit processors from AMD. 
There are no plans for supporting other architectures - yet.

Either way, assuming I didn't get that bit about the 386 wrong, I'll
commit it soon.
