Well, hard to say; sometimes the manufacturers claimed a "maximum" simply because the largest DIMMs around at that point were small; if you could get ahold of larger ones, they'd work.
With older machines, I'm not sure I'd recommend going with 512 meg DIMMs, because they can be a bit iffy with older equipment, especially if you're using an older OS. (I tried 512 meg sticks with Win98 on multiple occasions and ended up with unusable configs.) I'd say stick with 256 meg sticks instead, and see how that goes....on the understanding that maybe the 128 meg per slot limitation is on the motherboard itself. Maybe see if you can borrow the RAM from someone first.
