Question DELL XPS M200s with more than 64 MB Memory?

I was reading up on the Dell Dimension XPS M200s and why they say don't put more than 64 MB PC66 SDRAM on it.

They say because of the small processor cache, memory caching works for only the lower 64 MB range, and any memory above that runs cachless, taxing on the performance.

Since I can't get an answer there, and I am running Linux, I decided to ask here.

How much of a performance drop will I get with more RAM?

Will it really matter, considering I am running a 200MHz Pentium MMX?

I don't think that's going to matter as much, that sounds like it was written for win 9.x memory management and Linux handles things much differently, instead of loading things in use and flushing them when closed, Linux caches everything to RAM... really, I don't think there's going to be a performance hit. Actually, I'm running the same sort of machine, P1 200, 64Mb of PC66 SDRAM, and it runs fine. I did at one time have it with 128, and it ran quicker, mainly because it didn't have to page to swap to run X and a browser... but the thing is headless now.
