802.11n WIFI speeds

Does Fedora/Linux support the faster than 54 Mbit/sec 802.11n speeds?

My OpenWRT AP has a status page that claims that the 5 Ghz radio is
configured for a 150 Mbits/sec 40Mhz (double-wide) channel.  I'm only
seeing a 54 Mbit/sec throughput over WIFI though.  (Over ethernet to the
same router I'm seeing the expected 180 Mbits/sec to the internet.)

This is what lshw(1) has to say about the wifi card:

          *-network

                resources: irq:52 ioport:3000(size=256) memory:b2000000-b2003fff

Does this ring any bells?  I can easily believe that the faster speeds
are proprietary extensions but figured I'd check.
