Point taken... I got a MicroTek E3 here to play around with since so
many folks seem to like them. They are indeed cheap, but I really am
not impressed with them (after using thousand dollar scanners for 4

Back when I was trying to solve that problem, I was actually going to write
code to try to look in the kernel source directories and see. You can also
take the easy way out and default to 32K unless the user says they've

would be to read the kernel, but...
