Comment 8 for bug 521737

Thank you again, Alex, and sorry for reporting a non-bug.

For the record, and for the benefit of other people: the location for the firmware in Ubuntu is:

/lib/firmware/KERNEL_VERSION/radeon

For example:

leo@grisell:/lib/firmware/2.6.33-020633rc8-generic/radeon$ ls
R100_cp.bin R300_cp.bin R520_cp.bin R600_pfp.bin R700_rlc.bin RS690_cp.bin RS780_pfp.bin RV610_pfp.bin RV620_pfp.bin RV630_pfp.bin RV635_pfp.bin RV670_pfp.bin RV710_pfp.bin RV730_pfp.bin RV770_pfp.bin
R200_cp.bin R420_cp.bin R600_me.bin R600_rlc.bin RS600_cp.bin RS780_me.bin RV610_me.bin RV620_me.bin RV630_me.bin RV635_me.bin RV670_me.bin RV710_me.bin RV730_me.bin RV770_me.bin

Note that the Rxxxx_rlc.bin seem to be only required when using KMS, and are not currently provided with the kernel mainline ppa (all the other ones are). Also: performance seems to be better without KMS these days -- I get about 16 fps in WoP without KMS, and 20 with KMS, please see here:
