Errors:
5GHz Client Bridge (Routed) doesn't work at all. Downloads are extremely slow, no uploads possible at all. Long pings (~400ms), connection breaks.
With 2,4GHz the same configuration seems to work but with a limited speed.
I'm using the following tutorial for my setup: http://www.dd-wrt.com/wiki/index.php/Repeater_Bridge#Qualcomm_Atheros
My main router is a FritzBox 7390, supporting 2,4 & 5GHz up to 300/300 Mb/s - I'm able to get 12-15MB/s up/down with my laptop's Intel WiFi Link 5300.
I found out that for the 5GHz a relatively stable bridged connection could be established if TX/RX Antenna Chains were set to 1+3 (default: 1+2+3), but the speeds are about 4MB/s and the other parameters are: TX Rate = 6M (it seems to be a bug, it's always so), RX Rate = 121M, HT40, Signal Quality ~50%.
dmesg returns the following lines regardless of the TX/RX Antenna Chains (tested with different combinations):

I tested it also with following builds: r27506, r29721, r29739, r29968 & r30016. No luck...
