I'm afraid the integrated controller isn't supported. When all else
fails, check the source code:

You will see that the aic_7890 is missing from the typedef's.
I checked all of the kernel patches through the most recent, 2.1.107;
and, none of them include any change in this part of the code.
I confirmed that the drivers won't support the aic_7890 by asking the
author of the code. He said "Currently, none of the versions of the
aic7xxx driver for linux support the 7890 chipset."
One of the patches does add a "hack" so that the aic_7895 will work, but
it does not apply to the aic7890.
Dell is now using the integrated aic_7890 in all of their machines. I
have used an Adaptec 2940uw which is based on the aic_7880 chipset in
place of the built in controller in my Dell Workstation. It seems to
operate just fine with the Seagate ST39xxx series drives I'm using.
