Interesting that there are two places for unloading modules before suspend:
/etc/pm/config.d/
/etc/default/acpi-support
Does anyone know which is to be preferred?

@Ezra Reeves 
The out of the box driver for the Ralink 2860 card (rt2800pci) should work, at 
least if two things are taken care of:
1) there is a bug with pcie_aspm (PCI bus power saving) that is fixed with the 
kernel now in natty-proposed. This bug breaks the WLAN after a suspend when 
pcie_aspm is activated (e.g. on battery)

2) with PEAP with TKIP/MSCHAPv2 the module needs to be loaded with
"nohwcrypt=1" according to bug 777215.

If you find the out of the box module to have another bug it would be
helpful if you made a separate bug report about this with ubuntu-bug
linux so that it can be investigated and fixed.

Could you make your question about module unloading more specific?
