I have the same laptop running Debian and can confirm that you have to write some shell scripts to unload the PCMCIA drivers for suspend and resume to work. In addition to the PCMCIA drivers I also had to remove all the audio drivers for sound to work after resume. For me the magic combination was down the network, unload the WLAN, unload the audio, unload the PCMCIA, and then suspend. On resume it was; load audio, load PCMCIA, then load WLAN, and then fire up DHCP... Net result was a machine that suspended, but took nearly as long as shutting it down and restarting it. I don't recall using any kernel patches to do any of this, but as this is my sons laptop it has been a long while... so I could very well be wrong... as I do remember being leery to mess with ACPI as it's horribly broke on this machine and has been known to render them useless.
