You cant use dtp with 3524, use the set trunk */* nonegoitate dot1q to force it to trunk...
Also make sure you enble on the ge 0/1 on the 3524 as a switch port mode trunk with dot1q encapsulation That will force it to trunk, and life will be sweet. We use Dual 6509's with 10 3548XLs and its working fine.
