Have the same problem here - went down to site last week.
Had to stuff the following items in one bag :
- external 80Gb HDD and two 40Gb IDE HDD's for data backups
- 20 holder CD suitcase
- 8 240Mb CD's with utilities on 'em
- external DVD writer (as laptop's dvd rom have packed up)
- laptop
- power supplies and cabling for the lot
- pen and notebooks
- philips screwdriver
amazing that I passed security checkpoint at OR Tambo with that lot in my bag...

This is my assorted gear though I tend to leave one body at work during the week and cart the rest (sans the big lens).
