Done. Note: I changed is_reiserfs and is_e3 to "match" a partial string,
ie. udma66-reiserfs.

+udma100-ext3 variant of boot floppies uses a kernel patched with the latest
+ext3 and Hedrick's IDE patch
+
+The patch supports the Promise and Highpoint chipsets used on EIDE
+controler cards or builtin on modern boards with VIA chipset. If you
+install the standard kernel-image package you may not be able to
+reboot, since the standard package does not contain the necessary IDE
+patch.
+
+An additional extra feature is ext3fs (aka Journaling for ext2). This
+extension is up and backward compatible with ext2. Though you must not
+expect real reliability and safeness for your data.
+
+See the file 'kernel-config' for the complete list of devices included
+in this flavor.
+
+See the top-level README.txt file for a description of what the files
+in this directory are for.  To get a complete description of what
+files are required for various installation methods, see the
