Problems with 8.16.20 on amd64

[Michelasso <qzerty at gmail dot com>]

Hello,
I am using debian amd64 unstable in an Acer turion64 based laptop.
Everything was working with 8.14.13-2, I have upgraded to the new
version of the package since the new release of the driver is supposed
to support natively the 2.6.12 kernel (with the previous I had to
patch the sources)
First I had a problems in building the kernel module, since the
make.sh script looked for a
/usr/src/linux-source-2.6.12/include/asm/ioctl32.h that it is not
present in my sources; I have solved it with a symlink to
/usr/src/linux-source-2.6.12/include/linux/ioctl32.h

In this way the module is built, and I can load it without problems.
But the xorg server doesn't work because of a problem with the xorg
driver; in fact I have this in the log:


(II) Loading /usr/X11R6/lib/modules/drivers/fglrx_drv.o
Duplicate symbol rol_long in /usr/X11R6/lib/modules/drivers/fglrx_drv.o
Also defined in /usr/X11R6/lib/modules/linux/libint10.a

Fatal server error:
Module load failure

I have googled but I have found no references to this problem; any
suggestion will be greatly appreciated.
