BitSum do a PE xsum checker/patcher. You can get it with the free trial download of PECompact. Also, I found trying this with a blank user name gave ... intersting results.

And you can always patch the device driver in memory with another device driver. Or a ring0 privilege exploit.

What is this trick with the focs.dll, that causes OllyDbg to terminate. Where it says Bad or unknown format of 32-bit executable and the process exits

You can calculate the checksum for the sys file using LordPE
