html4.4ht contains non-ascii-chars and is 8bit-encoded. So luatex
doesn't like it (luatex expect utf8). You can try to save an
utf8-encoded html4.4ht version in a local tree in \tex\luatex\tex4ht
(or \tex\lualatex\tex4ht). Then luatex should pick up the
utf8-version and normal tex the other.

Btw: It would be useful if you always add a small example for test.

I tried a bit but didn't reach something conclusive yet (and I don't
have currently the time to do more). The main problem imho will be
with fonts: As long as you use the "normal" tex-fonts with tfm + 256
characters everything is fine. As soon as you use fontspec + system
fonts you will run into problem as the dvi will contain reference to
non-existing tfm's and -- more importantly -- to char numbers way
above 256. 

You can see some discussion about it here
