before you get too deep in this, and maybe I dont know about sun blades (definitely dont know much) but is this a sun machine with SPARC processor(s)? Has anybody installed this mess on a sun sparc, maybe sparc linux (solaris seems unlikely)? if there are success stories of mythtv on sun hardware, I will be pleasantly surprised.
then again maybe you just want to process the video files on this box. still do not see how you'll get this stuff to run. under x86 emulation, its going to be dog ass slow (which is pretty slow).

My roomate scored some equipment at a .com auction ... a LCD projector, some

Blade 1000. It has 2 36Gig FC drives, it has one SCSI connector open so we
can throw a system disk in there. it has 4 PCI slots and we were going to
try to use that for recording/encoding. It has room for one more drive in
the case ... I guess we could use an ext. SCSI cage ...
Keep in mind that Sun hardware is pretty crappy price/performance ratio compared to a modern PC. They're a tank and will run solidly forever, but they're not that fast CPU-wise. IIRC a blade 1000 is around a 600-1000MHz ultrasparc and would probably run linux quite well. Whether or not you could get all the mythtv stuff to compile with the endian issues is another issue. You'll also lose a lot of the spiffy optimizations (MMX, 3Dnow, etc) so it will probably perform slower than a comparable PC, even. If you just wanted to hang the filesystem/database off it, it'd probably work fine. If you want IVTV hardware support like for a backend, it's probably possible, but likely will take some hacking. If you want to crunch to DivX, I think you're SOL since it's a binary-only codec. XVid has source so you might have a chance there.
In any event, it seems like significantly more trouble than it's worth for a <1GHz machine. If it was a fire-breathing quad processor or had 1/2 TB worth of storage it might be more interesting.
That was my conclusion when I tried using a B&W G3 450MHz for a frontend. Although the box was much cuter and cleaner than a beige PC, a comparable PC (600MHz PII-PIII) is *much* more supported. Nothing more than tweak/hack value, really.
