[CentOS] question on minimal install using CF as /dev/sda

Hi all,

We're attempting to use CentOS 5.1 on a test platform which uses a CF 
card as it's primary storage.  (MB: ETX-LX)
The BIOS supports booting from CD and/or the CF.

Issues we've run into are:
During installation of CentOS 5.1, it appears all goes well through 
partitioning, package selection, interface configuration.  Once the 
install starts in earnest, errors pop up...a snippet is:

================
Traceback (most recent call first):
File
"/usr/lib/python2.4/site-packages/yum/packageSack.py", line 640, in 
returnNewestByName
    raise PackageSackError, 'No Package Matching %s' % name
File
"/usr/lib/python2.4/site-packages/yum/packageSack.py", line 318, in 
returnNewestByName return bestofeach.returnNewestByName(name)
File
"/tmp/treedir.29352/instimage/usr/lib/anaconda/yuminstall.py", line 
1093, in getBestKernalByArch
    pkgs=
ayum.pkgSack.returnNewestByName(pkgname)
File
"/tmp/treedir.29352/instimage/usr/lib/anaconda/yuminstall.py", line 
1102, in selectBestKernel
    kpkg = getBestKernalByArch("kernel", self.ayum)
File
"/tmp/treedir.29352/instimage/usr/lib/anaconda/yuminstall.py", line 1236 
in doPostSelection
    self.selectBestKernel(anaconda)
File
"/tmp/treedir.29352/instimage/usr/lib/anaconda/backend.py", line 177 in 
doPostSelection
    return
anaconda.backend.doPostSelection(anaconda)
==================

It appears that we're not writing to the CF and a driver is needed.  We 
have the driver, but are uncertain how to pass the information to the 
installer.  No Floppy is present.

Any thoughts or suggestions or pointers to resources would be greatly 
appreciated.
