WP 2.9.2 White Screens, tried everything, so far no fix

A site I haven’t touched since November suddenly White Screens the other day… The guys that now run it said the site is now down. I’m assuming somebody tried to update it (thought it was already on 2.9.2 previously but idk for sure) – but here’s the issue.
site: http://podcampaz.org
It’s a typical WP white screen issue… no page source… no /wp-admin either.

Here’s what I’ve tried:
– thought it was apache, but normal html/php files work fine w/o wp present
– If config.php is removed wp-load.php produces the “config not found” we can create one for you thing. I add wp-config back and it white screens.
– If I put bad database data in – there is no error, it still white-screens.
– I’ve tested no ?> at the end of the config file, I’ve removed the spaces at the bottom as that used to be an issue. Did the same for wp-settings.php & wp-load.php… nothing
– Removing or disabling all plugins has no effect obviously… I’ve reset the active plugins row in the database to a:0:{} still no effect
– removed/changed name of theme, nothing
– files are 2.9.2 – I’ve completely removed the whole site except wp-content and re-uploaded brand new files from 2.9.2.zip download.
– I’ve completely removed and replaced the wp-config.php and created new salt keys
– database version is currently 12329 (as it should be since 2.9x)
– I’ve added remove_filter(‘template_redirect’, ‘redirect_canonical’); to functions (still don’t think error is that far in to even load the theme fyi)
– I’ve tried bumping memory: define(‘WP_MEMORY_LIMIT’, ’64M’); no change
– Added debug to config: define(‘WP_DEBUG’, true); no change or errors
– permissions on all files seem fine and as far as I can tell never changed from when the site was working to now.

So… now what?. I’m officially stuck here guys… doesn’t happen often but whatever – lets get this fixed 🙂
