I downloaded the Alpine Linux 2.5.1 ISO images to test.

My test platform:
MSI Fuzzy 690T motherboard, uses AMD NB & SB chipsets
AMD Athlon 64 X2 cpu
onboard AMD 1200 Radeon video in AMD M690T chipset
SATA-II HDD (WD 320G Black 2.5 inch drive)
USB keyboard
USB mouse (Microsoft-compatible)
USB CD-ROM (via IDE-to-USB case)
Media: CD-RW
ISO: Alpine Linux x86 and x86_64 v2.5.1 ISOs

BIOS set to support USB-HID devices
BIOS set to boot from USB CD-ROM

(1) System will boot from CD
(2) System will display output to screen during boot
(3) Login prompt is displayed
(4) USB keyboard works fine before Busybox is loaded

What do you mean before Busybox, i guess you mean the bios (before the kernel is loaded)?
(5) USB keyboard is dead at login prompt
(6) Unable to login via USB keyboard

Other tests:
Other _current_ Linux ditributions have been tested
on the same hardware using both USB CD-ROM and USB
"stick" methods. All of these distributions will
support all of the devices listed above.

Example Linux distributions tested:
(either x86, x86_64, or both were tested)
Fedora 17
CentOS 6.x & Scientific Linux 6.x
Ubuntu 12.04 & 12.10
ARCH Linux
CRUX 2.8

Can you check which modules are loaded and compare it with the ones in alpine?
USB keyboard issue in Alpine Linux 2.5.1 appears in
both the x86 and x86_64 versions.

I noted from the Alpine Line 2.5.1 Git log that USB
device issues in Busybox have been seen previously.

Do USB issues still exist in Busybox as used by
Alpine Linux and is that being seen in my testing?

Thank you, JR

I'm also having issues with keyboards on different systems. Some systems it works as expected and some dont.
I don't think this is related to busybox, it could be a module or a bios issue.

What type of keyboard do you use, some keyboards need special kernel drivers.

--[my reply]--
I have tried 2 different keyboards. Here's a brief "lsusb" output for both:
Bus 002 Device 002: ID 046e:5500 Behavior Tech. Computer Corp. Portable Keyboard 86+9 keys (Model 6100C US)
Bus 002 Device 004: ID 0a81:0101 Chesen Electronics Corp. Keyboard

When I look at "lsmod" for either keyboard when they are plugged in, I see:

hid_generic            12493  0
usbhid                 46947  0
hid                   100366  2 hid_generic,usbhid

Size may vary by distribution. Ubuntu 12.10 in this case.

No other USB HID related modules are loaded. If there are any "special modules",
in this case, Ubuntu, they must be hiding somewhere. Here's a full "lsmod" dump:

Updating the BIOS is not an option for this motherboard per MSI.

Hope this helps.
