/etc/fstab is hardly guaranteed to be accurate either. The kernel mounts the root device based on its command line and any pivot_root() calls you make, not based on /etc/fstab. [In practice, I imagine most people don't lie to fstab. The fsck init script would get annoyed.] But the horse's mouth, in this case, is /proc/sys/kernel/real-root-dev, a 16-bit decimal int which represents a device number in MAJOR*256+MINOR format. There *may* also the 'root=' asciiz string in /proc/cmdline, which will be a 4-digit hex number, but that is not reliable - because of pivot_root() among other things. On my system, real-root-dev gives 8453, which means /dev/hde5, which is on ide2. According to /proc/ide/ide2/config, it is a PCI device of type 105a:4d30 [Promise Ultra100], so you can derive CONFIG_BLK_DEV_PDC202XX as well as CONFIG_BLK_DEV_IDEDISK.
