Even the driver name changes.(*)
At least both are 8bpp - but that is about all that is the same.
* Probably losing the pointer to the correct driver structure when restoring the original orientation (an 'extra' layer of indirection? points at the driver rather than the upper "driver shim"?) -
as I recall, the K4 is one that uses some "driver shims" on top of the K3 driver.
Or some other weird driver mess.
If the K4 was still in production, it might be worth fixing it.
[Whoot! 5,900! I gotta get a life.]
