Enough people asked about this for froyo, so I decompiled camalot's mod, and figured out how he increased the keysize (simple and elegant btw, grats on the find, I dug through smali files for weeks trying to change the keysize to no avail, lol.)
Anyway, here's his black/samsung skinned version for froyo, consider it a parting gift before I take a break from XDA for a while.
Please note, this zip will delete the stock/aosp keyboard (/system/app/LatinIME.apk) since on froyo it shares the same internal app name with the droidx keyboard. And also, I'm absolutely not responsible for anything that happens to your phone from installing this.
Download and flash with clockwork, cheers everyone, =)
