From my test on Chopin, no.
My test:
I have a custom 404 File Not Found that works.
In .htaccess I wrap the ErrorDocument declaration thus:
Code:
<ifModule mod_geoip.c>
ErrorDocument 404 /error/404.html
</ifModule>
note the '.c' at the end of the module name.
The Error document directive no longer works (it does if I use mod_rewrite.c or anothe mod I know is loaded).
