Thanks Ilia,

I think the most pressing issue here is to get users a working fb when they
boot in such a configuration (eg: Ubuntu's and Fedora's recent live cds).  Can
we use this bug to track updating the nouveau kernel module to not take away
the fb until it has guaranteed that it can be used for the fb?

Currently, forums are filled with recommendations that users boot with
nomodeset, which acts as a workaround because nouveau errs out earlier if KMS
is disabled.  It would be good to ensure that this error is similarly handled
early so as to not leave the user without an fb.


As an aside, I reconfigured for BIOS-emulation and have nouveau loading fine
here.  I'd like to get back to pure EFI, so is there an easy way to have
nouveau dump the firmware to disk for my use in EFI mode?  Is it exported in
/sys somewhere?
