I've got 2GB of RAM. I guess I didn't realize that having the mask doesn't restrict the output dataset. Of course, the values for most of the voxels are zero, but the file will still be very large.

I just set those two environment variables and then re-ran Case 2; here's what I got (same error as before):
++ Program 3dmaskave: AFNI version=AFNI_2006_03_21_1314 [32-bit]
+++ 246 voxels survive the mask
++ Program 3dDetrend: AFNI version=AFNI_2006_03_21_1314 [32-bit]
*** Illegal inputs to startup_lsqfit
** FATAL ERROR: Choleski factorization fails: linearly dependent vectors!


Any ideas?
