Subject: USB "raced timeout" errors on boot (2.4.11)

Whenever I boot with my brand-new 2.4.11 kernel, I get the following
series of errors (this snippet's from /var/log/messages):

Oct 9 18:28:13 fortytwo kernel: uhci.c: USB UHCI at I/O 0xef80, IRQ 10
Oct 9 18:28:13 fortytwo kernel: usb.c: new USB bus registered, assigned

... and so on. My USB devices seem to work just fine, but the errors
are kind of annoying (and add about 10 seconds to my boot time).

My USB bus is hooked up like this:
back of computer
`- my keyboard
`-my mouse

lspci -vvv:

(and my keyboard is a Microsoft Internet Keyboard Pro). Oh, don't boo
me... I'm using Linux, am I not? :)
