Did you ever get this fixed? I came across a similar issue upgrading to a customized 2.4.22 on a laptop with a PCMCIA modem. The problem was fixed by recompiling with CONFIG_ISA=y added back in - not quite sure why this worked, but it did; I only decided that this was the the most likely option by comparing a number of versions of the kernel I'd built...
