This is now fixed in CVS.

If you would like to test RAM downloadable secondary firmware, here are some example commands and dmesg output for this:

# compile kernel with download support (currently only for RAM download)
make pccard EXTRA_CFLAGS="-DPRISM2_DOWNLOAD_SUPPORT" sudo make install_pccard

# initializing card normally with flash versions

NIC: id=0x800c v1.0.0
PRI: id=0x15 v1.1.0
STA: id=0x1f v1.4.2

# just show firmware image info

utils/prism2_srec wlan0 RF010409.HEX
# this should tell which component is in question (station firmware
# v1.4.9) and which platforms (NICID) are supported. After showing
# firmware image info, the program compares requirements with the
# initialized card. If everything is OK, the output should end in "OK.".

# load the firmware image into card RAM and start using new version
utils/prism2_srec -r wlan0 RF010409.HEX
# after "OK.", the download starts "Downloading to volatile memory
# (RAM)."

# dmesg output shows download command and the memory areas. It then
# initializes the card again, but stops initialization early and starts
# writing image to card RAM ("Writing # bytes at 0x#"). After all data
# has been initialized, the card is re-initialized again, but this time
# with the downloaded image:

NIC: id=0x800c v1.0.0
PRI: id=0x15 v1.1.0
STA: id=0x1f v1.4.9

Version 1.4.2 did not work in Host AP mode, but the same card works fine after this RAM download.

One thing to note about this is that the image loaded to RAM will disappear in next reset (whether it is card removal or recovery attempt of some error state) and prism2_srec needs to be re-run to update the image again.
