Dear Maintainer,

I installed a netinst-jessie in EFI mode on an imac 27in 2009 with a Radeon HD
4670

02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
RV730/M96-XT [Mobility Radeon HD 4670]

All was succesful in command line.

When starting X, the system went into a black screen.
 I did a reboot in radeon.modeset=0 nomodeset and installed the non-free
drivers fglrx.
Unfortunately this did not solve the problem.

I am now running the system in Grub-bios mode and after following the above
steps
-radeon.modeset=0 in rescue mode and
-installation of fglrx drivers all is fine.

but in Grub-BIOS mode not in EFI as I was hoping to.

For more information do not hesitate to contact me.
