Yes. It can be done by changing omap mmc driver in linux kernel. The simplest solution is to comment lines 912,913 here
http://mxr.maemo.org/diablo/source/k...mmc/omap.c#908
Without those lines mmc driver keeps monitoring card change even if card door is not closed. This is not ideal but it allows you to access the card (and mount it manually to /media/mmc2)
I have done this and it works. The extra polling might (slightly?) affect battery life.

Alternative is to redefine mmc_omap_cover_is_open
http://mxr.maemo.org/diablo/source/k...mmc/omap.c#286
to return values you wish so cover open/close events are simulated. The easiest is probably to hook it to card door of second slot (by hardcoding slot value id) so both slots are checked when one door is opened/closed. I have not tried this.
