Wow, you mean to say that you can flawlessly S3 suspend/resume with kernel 2.4? I would assume that this is due to your laptop's support for S3 in BIOS. Not all laptops have this... see for instance what Ole had to do to get his working: http://home.cern.ch/mrohne/P2120/P2120_Linux_S3.html Drivers in the new kernel need to be able to suspend/resume (S1, S3 and S4) without more than the minimum required support in the BIOS.
