Hi,

I'm running the latest DragonFly BSD preview snapshot (July, 8) on my
Acer Aspire 1314LC laptop. 

I can't use my Prism wireless card because the pcmcia slot doesn't work.

According to dmesg there is a 'bad Vcc request'

cbb0: <O2Micro OZ6912/6972 PCI-CardBus Bridge> mem 0xc000000-0xc000fff irq 11 at device 10.0 on pci0
cbb0: PCI Memory allocated: 0c000000
cardbus0: <CardBus bus> on cbb0
pccard0: <16-bit PCCard bus> on cbb0
installed MI handler for int 11
cbb0: cbb_power: CARD_VCC_0V and CARD_VPP_0V [44]
cbb0: bad Vcc request. ctrl=0xf6bae908, status=0xffffffff
cbb_power: CARD_VCC_0V and CARD_VPP_0V [44]

The wireless card is not detected when inserted into the slot and there
are no messages from the kernel.

The complete /var/run/dmesg.boot can be found at:

http://spiro.fisica.unipd.it/~argentie/dmesg.boot


This is /boot/loader.conf:

### /boot/loader.conf

loader_color="YES"

vesa_load="YES"
splash_bmp_load="YES"
acpi_load="YES"

bitmap_load="YES"
bitmap_type="splash_image_data"

machdep.disable_mtrrs=1

kern.polling.enable=1

hw.pci.allow_unsupported_io_range=1
hw.pci.enable_io_modes=1

hw.cbb.start_memory=0xb0000000

hw.cbb.debug=1
hw.cardbus.debug=1
hw.cardbus.cis_debug=1
hw.pccard.debug=1
hw.pccard.cis_debug=1

# end of /boot/loader.conf


As you can see I tried the "hw.cbb.start_memory hack" which is suggested
in many articles on the web for FreeBSD. But I had no success.

This is my kernel config file:
http://spiro.fisica.unipd.it/~argentie/dflybsd_config

And the output of pciconf -l -v:

Thanks for the attention,

bye
