Precise Alternate USB install fails, expecting to find CD-ROM

USB install for Precise Alpha 2 Alternate i386 fails, expecting to find a non-existant CD-ROM

Detecting hardware to find CD-ROM drives......
Loading additional components.....

This is where it fails, after loading some.

Error message:
[!!] Load installer components from CD
There was a problem reading data from the CD-ROM
Please make sure it is in the drive. If retrying does not work, you should check the integrity of your CD-ROM.
Failed to copy file from CD-ROM. Retry?

On pressing Ctrl+Alt+F4, some additional information is available:

Occurs with Gigabyte G31 775, Foxconn 775, Gigabyte H61M 1155 systems. Guess it's universal

Still affects beta 1.

Still affects 12.04 release. This is manual FIX.

I stuck on that problem when building my mini-itx atom backend platform with RAID and LVM. Inspired by workaround of bug 976509 given in comment #8 I started filenames investigation. File name of missing package "fs-secondary-modules-..." was TRUNCATED TO 65 CHARS. In my case file on flashdrive looked like this:
"pool/main/l/linux/fs-secondary-modules-3.2.0-23-generic-pae-di_3.2.0-23.36_i386.ude"
but extension should be "udeb" instead of "ude"!
Note that you can find more 65-chars names truncated that wrongly ends with "ude", so search & fix them all.

12.04 alternate may fail later on installing package "xserver-xorg-video-ati" (bug #789898 resurrection?).
 In my case it was due to another wrongly mangled filename. I found package name misspelled, it was
"xserver-xorg-video-radeon_6.14.99~git20111219.aacbd629-0ubunt_i386.deb"
but should be
"xserver-xorg-video-radeon_6.14.99~git20111219.aacbd629-0ubuntu2_i386.deb"
note truncation before suffix "_i386.deb"

After that one I could successfully finalize installation.
