Okay since many people are having a hard time getting this to work (myself included until now) I thought I'd post the procedure here.

1 - Download the latest version of the Hex editor here.

2 - Locate the Camera Raw plugin in the /Program Files/Adobe/Photoshop 7.0/Plug-Ins/Adobe Photoshop Only/File formats/ folder, and copy it to a safe place for a backup (common sense)

3 - Open the Camera Raw plugin in the hex editor you downloaded (not the backup of course, but the one still located in the photoshop folder)

4 - Under "search" select find and click on the text string button. Type "Canon EOS D30" and click the "Text->Hex" Button then press okay.

5 - In the right panel you will see the entry for the D30 followed by the entry for the D60. Place the cursor over the D in D30 and type DIGITAL REBEL in all caps (or 300D if not in US). The new text should be replacing the old text. If not, reload and try again, but before you type hit the "insert" key to switch to replace mode.

6 - Once you type DIGITAL REBEL (you will have typed over part of the D60 tag too) the cursor should be on the space immediately following the L in REBEL. At this time, click the box the cursor is in on the left side (hex side) and type 00. For Digital Rebel users there will still be three blocks left of the D60 tag, just put spaces over them (or type 20, 20, 20 in the hex editor over the next three squares before the 00). 300D users will obviously have a different number of spaces left. Just copy over these with blanks the same way.

7 - Click save, and launch Photoshop. The Raw files will load now.

I don't know what everybody's problem is with the D30 color profile being applied to the Rebel. I simply adjusted exposure, white balance, and contrast...exported a 16-bit file, and adjusted levels and saturation in photoshop. The images look great! Now I can unsharp mask in photoshop without sharpening the JPG artifacts!

8 - If this thread helped you then please reply with a bump or no text (nt) message to keep it towards the top. There have been a lot of people having trouble with this (myself included) and with so many posts in the 300d forum this one will get buried quick. Try and keep it towards the top so everybody can get this working.

Good Luck!
