I haven't tried it, but you could try a plugin using hook location showthread_post_start and this code:

if($vbulletin->userinfo[usergroupid] == '1')
{
    $post_cachable = 0;
}

That might work for showthread.php but I'm not sure if there's anywhere else that might be a problem. I think a better thing to do would be to arrange for specific posts to not be cached, which can be done by setting $parsedtext = '' at hook bbcode_parse_start. The problem is that you'd have to figure out how to tell if a post has the quote tag in it. You could set $parsedtext = '' all the time and effectively turn off all post caching, but I don't know if you want to do that. I know my site has a lot of guest activity so i don't think we'd even want to turn off caching for guests.

(BTW, you can't check the usergroup to decide whether or not to set $parsedtext = '' or you'll end up with the same problem you have now).
