Several, it seems:
OpenSUSE 10.0

/dev/hda1       /               ext3    errors=remount-ro       0       1


I guess it's not a number on which to rely.

It's not an inode value.  Inodes are found in file systems, they're

not

device-related.  The number you see is the decimal value of a two-byte
hexadecimal number.  The hexadecimal number is the major and minor
numbers on the device in /dev.  For example, on one of my systems,
/proc/sys/kernel/real-root-dev give me a value of 24065.  Converting
that to hex, gives me 5E01.  So, device number 94, 01 in /dev is my

real

root device.  That just happens to be /dev/dasda1.

/dev/hda is my sole physical drive, hda3 contains my root filesystem.
