I have run WinSPMBT with both nVidia Fx5200 card and ATi Radeon 7000 (IIRC), both with 128MB VidRAM.
Both cards are among the cheapest you can get, and you may want to watch out for a fan-less version (as I did with both), which saves you troubles and noise with them.
Do avoid MX-cards under all circumstances, they're crap ...

But do not forget to add "real" RAM .. 128MB is barely sufficient to run Win98SE and Word (but do not put graphics into your docs, or you're into trouble..), but not WinSPMBT ...
And check the [vcache] settings in ... lemme think .. system.ini it was, IIRC. There should be some entry like
Code:
[VCache]
MinFileCache=24576
MaxFileCache=24576
This will result in Win98 using a fixed-sized file cache in RAM of 24MB size. If you do not set 'MaxFileCache', the cache size will happily grow to very large size, eating up your free RAM while running an APP and doing file I/O ...
