[gentoo-user] ati-drivers:legacy fail to build with kernel 3.12

[Helmut Jarausch]

Hi,

in "good" tradition the new 3.12 Linux kernel breaks  ati-drivers again  
(as always in the past).
Does anybody know about a patch to make
x11-drivers/ati-drivers:legacy
compile with linux-3.12-rc3 ?
Trying to emerge ati-drivers-13.1_pre897 (currently the only legacy  
driver)
with 3.12-rc3 gives

  MODPOST 1 modules
FATAL: modpost: GPL-incompatible module fglrx.ko uses GPL-only symbol  
'acpi_bus_get_device'

Many thanks for a hint,
Helmut
