PCMCIA and your custom RedHat 9 kernel

I recently wanted to compile a custom kernel for my RedHat 9 laptop. (For some reason, RedHat decided to omit NTFS support from their stock kernel, even though it includes just about every other module under the sun.) Much to my consternation, on reboot my PCMCIA cards no longer worked. :( The only change I made to the default kernel config was to add NTFS support, so I was rather perplexed.

Booting back to the stock kernel (ya gotta love grub!) revived my PCMCIA CardBus, but left me NTFS-less. (Please keep the "that's a feature, not a bug" comments to yourself...) The release of a security patch for the 2.4.20 kernel just increased my desire to get a custom kernel going.

Further investigation determined that the problem was a missing socket driver (yenta_socket) module. When the ds module tried to load, it failed because it couldn't find the socket driver. Manually loading yenta_socket then ds got everything working properly. But it didn't work at boot time, only if I manually loaded the yenta module.

I still can't figure out why this is the case, since my modules.conf and /etc/sysconfig/pcmcia files are the same with either kernel. But for what it's worth, adding this line:

    pre-install ds modprobe yenta_socket

to modules.conf solved the problem.

If anyone can shed any light on this, I'd be glad to hear it.
