Just installed SuSE 8.1 which works great except that I can't seem too get my ata100 (Highpoint Rocket133) card to load when I boot my machine.
I compiled the driver and it works. When I run insmod or modprobe manually I can mount my disks. But I don't want to do that everytime I restart my machine.
I've even run the install command to install the driver in the system:
install -d /lib/modules/.../scsi
install -c hpt302.o /lib/modules/.../scsi

Got any ideas?

In SuSE 7.x and 8.0 this worked just fine, and now in SuSE 8.1 I can't access FAT disks unless I'm root. This I find a bit odd.

All help or ideas openly accepted!

You could add the path in your rc.local script to load at boot time or make it available in your modules.conf or rc.modules file.. whichever one is available, not totally sure, don't use Suse but you should have an rc.local which could do the job just fine.

Adding the commando [modprobe hpt302] or [insmod hpt302.o] to the startup scripts works alright, but when the system then tries to mount the disks automatically from fstab it panics and goes into safe mode.
I guess that is because the module isn't loaded into the kernel or something. Know how to hack the kernel so that it supports my Highpoint card?

No need to hack the kernel, that just provides support which you already have. You'll just need to have the modules load before fstab mounts and reads the disks probably. Try to place those in whatever runlevel your booting into.
