Yes, not only 1.1.x, but also 1.2.x and 1.3.x(tested with:1.1.54, 1.1.59,
1.2.3, 1.2.6, 1.2.8, 1.3.3, 1.3.25).

yeah, i know what to do, but the problem is like this:
when i boot into linux-1.0, they are *perfectly* working..
but when i boot into 1.2.3 or something(having done *no* modifications)
they fail to work correctly.

I do have the IRQ *and* the port address set correctly, and i have
compiled kernels with fourport support.
Also, when the system boots, the kernel detects correctly the fourport card.
