I'd believe what you have read.

The general philosphy is that most device drivers are almost always
best built and made available as modules.

Besides, there really are distinct advantages in being able to
unload device drivers at runtime (eg, you can reconfigure the IRQ or
dma etc for the driver by simply unloading and reloading it -
without otherwise resorting to a system reboot which would be the
case if the driver was compiled into the kernel itself).

If you need to load any device drivers before actually booting the
kernel itself (eg, an nfsroot kernel which needs an ethernet
driver), then that problem is solved by creating (and making
available with lilo or bootp or whatever) an initrd image that can
preload the device drivers it needs before actually attempting to
mount the root filesystem.  (Fairly easy to do this with something
like redhat's mkinitrd utility).
