Suggestion 1:

You've probably already accounted for this, but here goes:
Does the BIOS setup allow you to auto-detect the disk? If so, does the BIOS
correctly auto-detect the disk? If the disk is not showing up in the boot time
summary, I would suggest the BIOS has not registered it. In this case, if
mke2fs gets its auotomagic info from the BIOS, I imagine it won't handle the
disk correctly

Observation 1:

> Units = cylinders of 1008 * 512 bytes

512 byte clusters? cf. below:

>diffie:~# df
>Filesystem           1k-blocks      Used Available Use% Mounted on
>/dev/hda3              1930691   1489423    341476  81% /
>/dev/hdb1               738608        24    701064   0% /mnt

mke2fs seems to be assuming 1024 byte clusters. This may be contributing to
the spurious size

Suggestion 2:
(If suggestion 1 and/or observation 1 are of no use)

Try it and see?
