udev/hotplug does abolutely the right thing.
The sda node is the whole disc. You may install a bootsector by
writing block 0 of sda, so you need this node to be created.
sda1 and sda2 are your data partitions. You can print the partition table
with "fdisk -l /dev/sda" and you will see two partitions there.
Maybe you just don't use the second partition now.

This is what udev creates for the first IDE disc:
brw-r--r-- 1 root root 3, 0 Nov 5 20:14 hda
brw-r--r-- 1 root root 3, 1 Nov 5 20:14 hda1
brw-r--r-- 1 root root 3, 2 Nov 5 20:14 hda2
brw-r--r-- 1 root root 3, 4 Nov 5 20:14 hda3
and this is the partition table:
Device Boot Start End Blocks Id System
/dev/hda1 1 992 499936+ 82 Linux swap
/dev/hda2 993 20368 9765504 83 Linux
/dev/hda3 20369 155061 67885272 83 Linux
