In fact, "dmesg | grep ppmc" should filter out just the ppmc-related lines. The "blah.ko module will not load" message takes a guess at the cause, but it is wrong in this case. What it really is saying is that module won't STAY loaded, ie. it found something serious wrong and aborted. The most obvious cause is it failed to detect any PPMC boards on the bus. Usually, when the diag can find the boards, EMC can, too. But, it is a different environment between RT and the diag program, which runs as a Linux user program with priviledges. When you check the dmesg output, make sure EMC is trying to access the boards on the 0x378 I/O port address.
Back in the old EMC1 days, these drivers did not require any kernel support to talk to the parallel port. Apparently now it does require some lower-level port drivers. You want to set the port to EPP mode in the BIOS setup screen, although the diagnostic program should have the same trouble if that were the problem. You say the diagnostic works.
