Maciej already offered to help fix the driver, so I think it will be ok.

On the other hand, it sounds like VirtualBox users should not actually try to
use the BusLogic driver with modern Linux guests. From what I can tell
from the documentation [1], VirtualBox only provides this emulation because it
was shipped with early versions of VMware and is supported by Windows 2000
and earlier, but not actually on any modern Windows guest. The VMware
documentation in turn explicitly says that BusLogic does not work with 64-bit
guests [2], presumably this applies to both Windows and Linux guests.
