udev not recognizing SATA cards/drives?

Installing gentoo with 2004.3 live cd, using kernel 2.6.10r1, found that though the livecd does recognize the Sata card and drives, the weren't available with the kernel i built (using an IDE/ATA as a boot drive).

After many kernel recompiles, i finally found and used the modprobe command, and wallah! the drives were now usable with my kernel.

I should not have to use modprobe; is this a problem with udev ( should I change the udev.config?) or cold or hotplug issue?

just put the modules in modules.autoload.d/kernel-2.6. That way it will still work even if you upgrade hotplug or decide not to use it later on.

and later i found i had to put coldplug in the rc-scripts - duh!

You may find that running both hot and coldplug slows down your system.
I don't like coldplug at all; it is simpler to manually add the modules to modules.autoload. The exception would be if you were constantly changing that hardware the system booted up with.
