I compiled latest gentoo-soucres kernel (from 25.08.2003). Build agpgart. Then I emerged xfree-drm with USE="radeon". Here is a snippet of the compile process: <snip> * Building DRM... gcc -O2 -Wall -Wwrite-strings -Wpointer-arith -Wcast-align -Wstrict-prototypes -Wnested-externs -Wpointer-arith -D__KERNEL__ -DMODULE -fomit-frame-pointer -fno-strict-aliasing -DCONFIG_DRM_SIS -DMODVERSIONS -include /usr/src/linux/include/linux/modversions.h -DEXPORT_SYMTAB -I/usr/src/linux/include -c radeon_drv.c -o radeon_drv.o In file included from radeon_drv.c:48: drm_lock.h: In function `radeon_lock_take': drm_lock.h:57: warning: implicit declaration of function `cmpxchg' </snip> when I issue: cat config | grep CMPX I get no entry. Is that the problem? I found an entry at: http://www.mail-archive.com/gentoo-user@gentoo.org/msg13475.html After "emerge xfree-drm" a "modprobe radeon" shows: <snip> /lib/modules/2.4.20-gentoo-r5/kernel/drivers/char/drm/radeon.o: unresolved symbol cmpxchg /lib/modules/2.4.20-gentoo-r5/kernel/drivers/char/drm/radeon.o: insmod /lib/modules/2.4.20-gentoo-r5/kernel/drivers/char/drm/radeon.o failed /lib/modules/2.4.20-gentoo-r5/kernel/drivers/char/drm/radeon.o: insmod radeon failed </snip> Before that I had to insmod agpgart with the unsupported parameter. (because of the Sis Chipset) When I am at home I will post my exact kernel version. But I got the same error as above. I searched the web but I haven't found a solution for that problem anywhere. The ati-drivers doesnt't work either because I have got a PCI Card and the ATI drivers are only for AGP. Btw, Xfree86 works and starts up with DRI disabled. But that is not what I want ;-) Thanks. gonzo P.S.: Perhaps that's important: I have got a Celeron 1.8Ghz cpu SiS 651 chipset (but not using the onboard vga) ATI Radeon 9000 PCI (It's a MSI 651 Hermes barebone Pc System)
I'll be putting -r7 of xfree-drm out before long, which should have better support for direct rendering on PCI cards. I'll post to this bug once it's committed so you can test.

Disabling DRI. and finally here comes syslog: agpgart: Unsupported SiS chipset (device id: 0651), you might want to try agp_try_unsupported=1
As for the cmpxchg issue, the mailing list post you referenced sounded useful. Do you have your processor set correctly (e.g., PentiumIII/Celeron, Pentium4, or whatever yours is) in the Processor Type and Features section of make menuconfig?
Sorry kernel guys, didn't mean to CC you here.
I confirmed that this issue is due to having 386 set in Processor Type and features (it should be 486 or higher), so I'm closing this.
