Summary:
1) Chris has ASUS WL500pv2 with OpenWRT
2) This is router with Broadcom 5354 SoC and LP-PHY card
3) Firmware 410.2160 (broadcom-wl-4.150.10.5.tar.bz2) works OK
4) Firmware 478.104 (broadcom-wl-4.178.10.4.tar.bz2) causes OOM
Larry was testing his LP-PHY with kmemleak but didn't find anything.
Chris traced a lot of skbs being allocated before OOM (500+).
I suspect that with new firmware we provide slightly different RX
packets to mac80211 and there is sth wrong with mac80211 causing SKBs
not being freed. I don't have any other idea how changing firmware
could cause out of memory problems.
The alloc code is question is dma.c::~585
skb = __dev_alloc_skb(ring->rx_buffersize, gfp_flags);
I've written patch to dump data we provide mac80211. My hope is to
notice differences in that data between older vs. newer firmware.
Chris: could you try attached patch and provide dmesg from older and
newer firmware with this patch applied?

I applied the patch to the latest OpenWrt trunk. (rev 26588) with
compat-wireless 2011-04-06

It's weird you got only 5 of my error-debugging messages. Earlier you
got ~500 allocs before OOM *and* I expected each alloc to be followed
by my error-debugging messages.

Here I also expected to get 500 messages, unless there was not traffic
in the air.
Conclusions:
1) I need to prepare another patch with more detailed debugging
2) There is difference in channel between firmwares. Channel is
(chanstat & 0x7F8) >> 3. In case of 478.104 it seems to got channel
(0x1000>>3)==1, in case of 410.2160 it seems you got channel
(0x51>>3)==11. Do you use AP mode? Did you switch between channels?

I am using a more recent version of compat-wireless, with quite a few
changes in mac80211
The configuration I am testing is the standard config from the openwrt build:
* AP (Master) mode.
* Channel 11
* No Encryption
* Single SSID
* Bridged
If I take it out of the bridge, it takes a little longer to fail:
STA / AP mode doesn't appear to make any difference.
The Channel is "defiantly" set the same between firmware versions
I think that you may be on to something with that.
