The flash memory was reduced starting (casually), the WRT54GS V.5 version (apparently to cut down on costs (mine costed me $60 two years ago)
And DD-WRT says V.7 also supports it (though I strongly recommend you against it). But remember that in the electronics world, some people (like me) get screwed by firmware changes, and some people actually get more out of their product.
One thing I do tell you is that if you do know what you're doing (I installed it just because it seemed better, and I kinda hated default FW), you are gonna get a lot more out of your current router (it has lots of functions that I don't know about/care to use)
But remember that at best, new Firmware can't help internal HW problems (if you do have them, firmware won't probably fix em)
Edit: All WRT54XL (ending with L support open firmware)
