MAJOR SD Card Memory Usage
 

i have BigJ's 3.5 1.6u ROM. i can have 23mb program memory on device, when sd card is inserted, i have 12mb program memory. Makes for slugish ppc usage. also sluggish wake from sleep mode. removing cards really solves the memory leak.

this is on 2 ppc set up identical, 2 1gig sandisk mini sd cards 1 80percent full, 1 10percent used.
