[arch-general] System upgrade fails

[Manolo]

Hello, i´ m getting this message when i try to upgrade my system (pacman -Syu):
I have the system in spanish, so i write a translation of it:

:: Starting full system upgrade...
resolving dependencies...
checking for conflicts...
error: fail to prepare transaction (couldn´ t satisfy dependencies)
:: ipw3945: needs kernel26<2.6.27

I think ipw3945 is something about my network card, but whatever it
is, it´s not listed in the repositories (pacman -Sl | grep ipw -->
ipw2100-fw and ipw2200-fw). And my kernel is 2.6.26-ARCH, so i think
is a kernel26, <2.6.27, right?
Anyone with the same problem?? Can i uninstall the package without a problem??
Thanks.
