I'm not sure if this is still relevant in this topic but I run Win98 on a PC with 1.5gb of ram & 256mb video card without problems. To do this do the following. Basically, with 1 Gb or less of RAM in the PC go to Msconfig and in the advanced tab choose the option that lets you limit the amount of RAM Win98 will use. Check the box and type 999 in the number box. Then apply and close. Reboot the machine. If all is okay then shutdown the machine, add your extra RAM and reboot. Your PC should work fine from here on, no need for RAM disks etc. Changing Vcache is about the only thing I also did, I set Vcache value to MaxFileCache=128000. Of course the extra RAM is there for when I run XP etc. Win98 doesn't use it.
