Submitted By: Jim Gifford <jim@linuxfromscratch.org>
Date: 05-28-2006
Initial Package Version: 0.97
Upstream Status: Unknown
Origin: Fedora and Mandriva
Description: This patch fixes issues with disk geometry not being
detected properly. Part of this patch also fixes
gcc 4 compile errors, which are a part of the issue.
