mesh + ap mode at the same hardware

Hi,

I'm able to use open802.11s mesh networking or accesspoint-mode(with hostapd) on my D-Link DWL-G122 USB wireless network card. Is there any way to use both modes at the same time on this network card?
I know, my Linksys WRT54GL can do accesspoint-mode and client-mode at the same time.
Adhoc-networking would be an alternative if hostapd wouldn't work.

Thanks,
