Merged in cleanup changes from osd branch (nw)
(MESS) Fixed doubled tag definition. (nw)
03447: gauntdl, gauntdl24, gauntleg, gauntleg12: Texture with alpha channel is not drawn properly. [Phil Bennett]

voodoo - Fixed alpha test to run on the alpha combiner output and not on a_other. Do the test before the color combiner steps to potentially save some effort. [Phil Bennett]
sblaster: fix irqs and 16bit dma (nw)
(MESS) super80 : oops!
(MESS) fanucspg: Better colors from new reference. [Guru, R. Belmont]


nw: If you're bored and can read segmented 16-bit x86 decently, I could use some help figuring out what's happening when it (I think) attempts to boot off the '765 and bring all those other chips into play.  (Change test_r to return 0x80 to observe).
(MESS) Obvious digital RGB is obvious (nw)
