The patch allows me to boot 2.6.18 and 2.6.19-rc2 on a Blade 100
(kernels built with gcc-4.1.1 on Gentoo).

In what may be in relation to the loosening of the resource conflict
message suppression, I see two call traces related to registering
devices in 2.6.18 that I don't recall seeing in 2.6.17 and one IRQ
handler problem  in 2.6.19-rc2.    If these aren't related, then
just ignore this part of the message :)  Errors are below:
