I also have that. To test it out, I moved R600_rlc.bin from
/lib/firmware/radeon, and X still comes up. So it has been pulled into
the kernel.
But wait, whilst screwing around, I noticed that the compile pulls in
every blob in the /lib/firmware/radeon directory...
BARTS_mc.bin CAYMAN_pfp.bin JUNIPER_pfp.bin SUMO2_me.bin
BARTS_me.bin CAYMAN_rlc.bin JUNIPER_rlc.bin SUMO2_pfp.bin
BARTS_pfp.bin CEDAR_me.bin PALM_me.bin SUMO_me.bin
BTC_rlc.bin CEDAR_pfp.bin PALM_pfp.bin SUMO_pfp.bin
CAICOS_mc.bin CEDAR_rlc.bin R600_rlc.bin SUMO_rlc.bin
CAICOS_me.bin CYPRESS_me.bin R700_rlc.bin TURKS_mc.bin
CAICOS_pfp.bin CYPRESS_pfp.bin REDWOOD_me.bin TURKS_me.bin
CAYMAN_mc.bin CYPRESS_rlc.bin REDWOOD_pfp.bin TURKS_pfp.bin
CAYMAN_me.bin JUNIPER_me.bin REDWOOD_rlc.bin
I removed all but R600_rlc.bin (the one the laptop graphics chip
requires) from /lib/firmware/radeon, rebuilt the kernel, and rebooted,
and now X comes up fine without the libudev files. This is weird. The
only thing I can think of is...
* with only one binary blob. it "just works"
* multiple blobs should not be included in the kernel, otherwise it gets
confused. If multiple blobs are included, there's a fallback
mechanism that uses udev to figure out exactly which graphics chip the
laptop has, and which of the built-in blobs to use.
So my laptop is now entirely udev-free.
