> There are a number of systems and cloud providers out there
> that have nomodeset hardcoded in their kernel parameters
> to block nouveau for the nvidia driver.  This prevents the
> amdgpu driver from loading. Unfortunately the end user cannot
> easily change this.  The preferred way to block modules from
> loading is to use modprobe.blacklist=<driver>.  That is what
> providers should be using to block specific drivers.
>
> Drop the check to allow the driver to load even when nomodeset
> is specified on the kernel command line.
