Did you upgrade to modutils-2.1.112 ? If not, you'll never get 2.1.1xx
modules to work. And if you install the new modutils you have to upgrade
mkinitrd too, if you need some modules loaded in the initial ramdisk
(eg. if you have a SCSI boot disk). You'll find a complete list of the
things you need to get a working 2.1.1xx in
/usr/src/linux/Documentation/Changes (assuming you unpacked the source
:)
Another thing to remember: if you switch back to 2.0.x kernels, you have
to downgrade modutils and mkinitrd: fi you don't, expect weird things to
happen with your modules...
Pay attention to init scripts, too: 2.1.1xx have completely new routing
scheme, so if you have explicit routes you'll see them doubled because
the kernel makes appropriate routing by itself only if you ifconfig your
interfaces. To work well with new routing scheme you'll need the new
iproute utils, you can find them in any sunsite mirror. If you use IP
aliases you'll never see them with route or ifconfig: you'll need
iproute for that too: alias are there (you can ping them) but old
net-tools can't see them.
