crucial.com says GRX500 family all have...

: System Info:
: 
:     * Maximum memory: 512MB
:     * Standard memory: 256 or 512MB removable
:     * Slots: 2 (2 banks of 1)
:     * Explanation of memory terms

per http://www.crucial.com/store/listparts.asp?Mfr%2BProductline=Sony%2BVAIO+PCG-GR%2FGRS%2FGRV%2FGRX+Models&mfr=Sony&cat=RAM&model=VAIO+PCG-GRX500+Series&submit=Go#specs

Of course, I'm pretty sure my grx-560 came with 128M installed and
128M more via mail-in rebate.

As John noted, no 512M listed at crucial.com, but pricewatch
lists 512M PC2100 memory (under "laptop memory", "512M for sony") 
from $77 (incl domestic shipping).  Will this work or does GRX500 
series need special memory?
