Stock kernel and backports for wireless drivers

[grendelmint]

I run the stock kernel on my 32 bit KDE install. This is 3.2.0.23.36 To get support for my RT5370 wireless USB (claimed by rt2800usb) I need to get the linux-backports-modules-cw-3.3-precise-generic install. However this will prompt to install kernel 3.2.0.35 as the latest version of the precise package is 3.2.35.40. Synaptic by default installs the latest version of a package. I'd prefer to stick to the stock kernel for now so I want to know how to get the precise package for my kernel install. I tried to install the only 3.2.0.23 backports package and that is linux-backports-modules-cw-3.3-3.2.0.23-generic. The latest version is 3.2.0-23.6 When I do this I get complaints when I try to start the rt2800usb module about version mismatch. So I'm guessing the backports doesn't match my kernel version. Am I forced to upgrade my kernel?
