I'm pretty sure A-Eon, who are selling the AmigaOne X5000 based on an
e5500 core, funds the work of some Linux people to keep Debian up to date
for that system. And that's a pretty juicy multicore desktop machine, with
PCIe slots, RadeonHD videocards and everything, yet no Altivec.
Based on their earlier activities, I'd guess A-Eon would be willing to
support the right person with hardware, if this makes the difference.

I think until some larger company backs it, or there's mass demand, like
with other release versions, it won't happen anyway. I agree though, that
the target needs to be redefined, other than "keep those old Macs running
somehow".
But it's still ironic in the light of this discussion that one of, if not
the strongest desktop PPC box one can buy these days has no Altivec. And
there are much smaller OSes than Linux which somehow still manage to
handle this situation.
Just my two cents...
