The dc395x_trm kernel module supports the very popular range of Tekram PCI SCSI controllers. To date, this module is still not in the official kernel tree, but it would be fantastic if this driver could be packaged with Red Hat Linux. Its URL is: http://www.garloff.de/kurt/linux/dc395/ I spend a *lot* of time building this driver every time a new errata kernel is released. :-(
Our default policy is not to add drivers that have not at least been submitted upstream. If they have been submitted and denied, we usually don't include them, either -- there's generally a reason. Adding drivers in that aren't included in the upstream kernel is intended as a TEMPORARY solution while they are being added to the upstream kernel only.
