NetBSD marks as unknown the partitions with a DOSTYPE that is unknown to
NetBSD. The known DOSTYPEs are for NetBSD1.4.1 :

 - DOS\x (for AmigaOS filesystems upto DOS\5), muFS (MultiUser Filesystem)
 - NBR\x (NetBSD root partition), NBU\x (NetBSD user partition), NBS\0 (NetBSD
swap partition)
 - UNI\2 (AMIX partition)
 - LNX\0 (Linux partition, used for ext2fs), SWP\0 (Linux swap partition). Since
1.4.1

The partition you try to mount, may have a wrong DOSTYPE, It should be LNX\0 but
I think it is not really needed. I used to mount my Linux partitions with
DOSTYPE=UNI\2
before NetBSD1.4.1.

Another think is that you don't have to compile a kernel with support of ext2fs,
because you may use the ext2fs.o kernel module and load it only when you need
it.
I use kernel modules ext2fs msdosfs and cd9660, which I never really need at
boot
time.
