For an ISA or X-bus part the number of address lines. 
  4Mbit is the limit in a normal 32pin configuration.
For an LPC part the size of the chip you can buy.

AMD and Intel have switched over to using the LPC bus in their
chipsets a year or two ago.  I don't know what VIA has done, but
I expect their are also using the LPC bus by now.
