Ok I found the solution of the problem.

As I said the laptop hangs on -STABLE too when I add sound to the kernel
config. I even tried to add PCI_ENABLE_IO_MODES and the kernel lock up
at boot too.

In browsing in src/ changes on -CURRENT, I noted that PCI_ENABLE_IO_MODES
is a sysctl variable since beginning of August and the default value is
1. Setting at boot hw.pci.enable_io_modes=0 fixed the problem.
