Okay, here's what our friends on the QEMU side said...

Has anyone thought about writing a QEMU BSP for RTEMS?  I'm not a very
good programmer..

    You need to specify a connection method for the nic.  qemu has vlans
now that organize the internal network.  The default qemu uses with no
-net arguments is -net nic,vlan=0 -net user,vlan=0.  This groups a nic
and a connection method (slirp) on vlan 0.  If you want to use tun/tap
networking specify -net tap instead (along with -net nic,...).  Your old
line might look like the below:

qemu -M isapc -net nic,macaddr=00:80:7F:22:61:77 -net
tap,script=~joel/qemu-work/qemu/qemu-kit/tunconfig.sh -m 4 -serial stdio
-fda /home/joel/qemu/grub144

Although I'm not sure what the old script format looks like - there are
example qemu-ifup scripts about the net.

Please link that page here so it can be reviewed for correctness.
