14 No, in my case I have a "radeon" card and the xorg was looking KMS in the kernel.
15 cat .config |grep KMS
16 CONFIG_DRM_KMS_HELPER=y
17 CONFIG_DRM_RADEON_KMS=y
18
19 After enabling KMS some might notice 1.5min delay when booting after kernel display the message:
20 Switching to clocksource tsc
21
22 Solution:
23 emerge: x11-drivers/radeon-ucode
24
25 in kernel .config:
26 Device Drivers:
27 - Generic Driver Options
28 [*] Include in-kernel firmware blobs in kernel binary
29 (radeon/R600_rlc.bin) External firmware blobs to build into the kernel binary
30 (/lib/firmware) Firmware blobs root directory
31
32 Run "dmesg" to see exactly which driver is the kernel looking for.
33 In dmesg after: Switching to clocksource tsc
34 you will see the driver name.
