Php.ini / htaccess conflicts on godaddy.

I’m not real sure where to ask this, since it’s only half a wordpress problem I’m having. I run a bunch of sites on my godaddy hosting (I know that’s half the problem, but I’m not gonna transfer). I have a custom php.ini file to up my upload size for DJ mixes. That portion works fine. However I have a conflict from my htaccess file. All my sites are in there own subdomain, and wp in it’s own directory. I wanted to run a mediawiki website and had to add modifications to my htaccess (in the overall root). So now mediawiki and wp play nice…except one thing. There are 2 lines of code in my htaccess that cause my php.ini to be ignored, killing my upload limit. Here is the code that kills my php.ini:

RewriteCond %{HTTP_HOST} ^rvoodoo\.com [NC]
RewriteRule ^(.*) http://www.rvoodoo.com/$1 [R=301,L]

# 1 YEAR
<FilesMatch "\.(ico|pdf|flv)$">

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

AddHandler x-httpd-php5 .php
AddHandler x-httpd-php .php4

# BEGIN WordPress

# END WordPress

Now, if I remove the 2 lines that start with AddHandler, my php.ini file controls my upload size again, but mediawiki won’t work. When I have them in, my wiki works, but my upload size reverts to godaddy default (8mb). The only reason I need those lines of code is to make mediawiki play nice on godaddy. Anyone who actually knows code know of any way to rectify this?

http://www.rvoodoo.com is the site, although I guess it doesn’t need to be seen as everything looks right.
