Does the controller show up on a hardware listing (i.e. on the boot
screen or via hwconfig)?  If not, the kernel can't find the controller.
If so, it's probably a mismatch in the I/O address.

My guess is that it's an I/O address mismatch; what I/O address do you
have it set for?  The Compaq controllers I've configured only have two
settings for I/O address (0x200 or 0x300), IRQ (3 or 5), and DMA (1 or
3).  The default I/O address for the cartridge tape driver is 0x338,
so try reconfiguring the tape driver to use 0x200 or 0x300, whatever
the controller is set for, and see if that helps.
