non-device code. * Re-implement the method dispatch to improve efficiency. The new system takes about 40ns for a method dispatch on a 300Mhz PII which is only 10ns slower than a direct function call on the same hardware. This changes the new-bus ABI slightly so make sure you re-compile any driver modules which you use.
