Your patch looks fine, and I think it will solve my problem, but I haven't 
been able to test it. Before accessing DR2, the program tries to read/write 
from the interrupt vector table, which results in an exception and the 
debugger being launched.

I'd try to implement support for that in wine, but I don't know where to 
look... I basically need to be able to read/write the interrupt vector table 
(for int 0x00 here), AND to execute the modified interrupt vector when a 
division by 0 is executed. Any idea ?
