Let's try things manually?

Check if  iptables is setup as in
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
(I used webmin to check firewall settings not sure how else to do it)

If host tun0 is 192.168.1.10, Win98 should be configured staticly to 
192.168.1.<anything but 10>
Set win98 gateway and dns server to 192.168.1.10.

Shutdown Windows, in terminal as root do

/etc/rc.d/init.d/iptables stop
echo "1" >&/proc/sys/net/ipv4/ip_forward
/etc/rc.d/init.d/iptables start

verify that the contents of /proc/sys/net/ipv4/ip_forward is "1"
if content is "0" then ip_forward is not being set, and tun will fail.

start qemu with -n <path to ifup script> (make sure -user-net is not included 
in start command)

If this works then the problem lies in your ifip script(s). If not, I'm lost.
