What do you think your "fix" to vsprintf will do?

Enable me to print numbers in decimal that are longer than 32 bit.

Forget it. I will not add "long long" support to printf without a really good reason.

That's ok. That is the reason I split the patch into two parts. The IDE patch works without it, but will not be able to print sectors over 32bit. (That is a 2.1TB disk, so it wont be a problem for a few years :)
