Embperl 2.0b8, which I will release during the next days, works with
Apache/mod_perl 2, but only in the prefork mode. This is because to really
use mod_perl in the threaded mode, you need Perl 5.8.0, because while 5.6.1
works, regular expression are really not thread safe in 5.6.1 and (and
that's more imported for Embperl) there are no shared variables between Perl
interpreter threads. Embperl require these shared variables, because the
cacheing should of course not per thread, but the cache should be accessed
by all threads.
I currently working on getting Embperl running with Perl 5.8.0 RC1 and my
plan is to have a threadsafe version of Embperl 2 ready, when the 5.8.0 is
out, maybe earlier.
Gerald
P.S. Because of the regex threadsafe problem in 5.6.1 I would currently use
mod_perl 2 in prefork mode to get familar with mod_perl/Apache 2 and switch
over to threaded mode when 5.8.0 is out.

Yes, the final release of mod_perl 2 will not run on any Perl before 5.8.0
when Apache runs in threaded mode. On Windows Apache always runs in threaded
mode, because Windows doesn't have a fork system call.
