What serial options have you got in the kernel config? Are relevant modules getting loaded?
What's the output of dmesg | grep -i serial -A 5?
Have you got ISAPNP enabled? I ask because of this post.

Do you have in the kernel choose the option "Charakter devices -> Serial drivers -> 8250/16550 ..."?

In 2.6 you have all those things under /sys instead... there is, believe it or not, a reason devfs is deprecated.
Anyway, you have the serial ports under /sys/class/tty/ttyS[0-7]/dev
