I installed Qubes 3.2 on my old Sony Vaio S without problems; it has a i7 620M CPU which supports most of the requirements. The graphics card (an Nvidia 310M) works better than in Linux Mint 16, where I had to insert an EDID image in X11; the HDMI connection allows me to use a Dell 23' monitor at native resolution. The wlan is not detected (IWI 2200BG) nor the integrated sound card, I think.
Thank you, I run your suggested command; sounds seem to be functional now (perhaps also before the upgrade), however the wifi is still not recognized, or at least I am still not able to see the wlan0 interface using "ifconfig -a" from the untrusted terminal and to bring it up, only eth0. No problems for me, the ethernet is enough; I will study Qubes network configuration.
P.S.: video card is ok, but the proprietary Nvidia driver still do not recognize my laptop monitor; I suspect that I would have to patch X11 configuration again ...
