So, the clock speed has been capped to prevent file corruption, but this clearly isn't the solution to the problem as it now appears to be worse than ever - I hope the solution won't be to cap the speed even lower. :(

Wow, that's some way scary stuff. I've got a 4gb SDHC card in my n800 
and the patched kernel and I haven't had any corruption yet, thankfully 
(they're expensive!).
Is this a maemo only thing? Or is everyone in the linux community 
experiencing the same issue?
Could it be an issue with bad RAM on select n800s? When my RAM has gone 
bad in the past, I get disk corruption and all kinds of odd side effects.
