    The BIOS check is a must, it checks bit #0 of MSR_IA32_FEATURE_CONTROL,
    if it set this means that software cannot write to the MSR. If bit #2 is
    clear too then when executing vmxon you'll get #GP.

    So the check should better be there...

    I have some problems on Thinkpad z61t with Core Duo T2500.
    /proc/cpuinfo shows "vmx" in flags, but module refuses to load:
    [17462106.632000] kvm: disabled by bios

    I wandered around BIOS setup (latest version), but didn't found
    anything about virtualization. Is BIOS check really necessary?
