I have a T22 and run 2.4.20-pre5 and 2.4.19-pre8 with no patches and
have no problems resuming from suspend.

My system is set up to always switch VTs (away from X) when it suspends
and back when it resumes.

All I can suggest is that you try 2.4.19 without any patches, then with
the rmap patch and then with only the USAGI patch and see if that makes
any difference.
