[tex4ht] biblatex, biber, and htlatex

The following minimal example, compiled with biblatex v. 1.7 and 
biblatex.4ht from 2011-11-10-03:54, stops with the error:

! LaTeX Error: Missing \begin{document} in `'.

The problem seems to be created by the "defernums" option. A similar 
problem appeared about one year ago, your solution then was the following:

"
The problem was checksum macros, which Eitan had redefined in 
biblatex.4ht. That seems superfluous and erratic with the current
revision of biblatex.sty. TeX4ht can very well make use of the original 
definition in the package, I believe.
"
