Its a typo. I googled STA-G5400 and got "SimpleTech STA-G5400/512 512MB PC3200 DDR 184pin DIMM". This is Power Mac Ram. Even if they upgrade the RAM in the PowerBook when the put a G5 in it, it will be a smaller more mobil RAM.
That is a typo. If one wants to speculate, possible release dates for Powerbook G5s:
1) WWDC 2005 - very unlikely, 10% chance PB G5 will debut by this time
2) MacWorld 2005 Paris - unlikely, 25%
3) MacWorld 2006 SF - unlikely, 50%
4) WWDC 2006 - very likely, 75%
5) MacWorld 2006 Paris - likely, 85%
6) MacWorld 2007 SF - likley 95%
7) WWDC 2007 - very likely 100% chance PB G5 will debut by this time
