The fsbmodmount example kernel uses the netbsd/freebsd filesystem code.
When you try to mount an ext2 filesystem, it fails. If you want to use
an ext2 filesystem, you need to replace the call to start_fs(). At the
moment, no one has contributed a version of start_linux_fs(), so you will
have to take a look at startup/start_fs.c and modify that to use the linux
FS code.
Also, your spec for the PARTITION_NAME above is wrong. Should be something
like this for a BSD disk.
#define DISK_NAME "hda7"
#define PARTITION_NAME "a"
where "a" is the partition part. For your linux disk, the PARTITION_NAME is
probably null though.

I refer you to:
http://www.cs.utah.edu/flux/oskit/html/oskit-wwwch1.html#x4-120001.6
Environment variables in the example kernels are specified on the command
line. The multiboot startup code turns those specifications into C style
environ vars. For example:
fsbmodmount DISK=hda7 PARTITION=a -- <other args>
