If you need to find out more information about a linux kernel module you can use modinfo:

[root@localhost scsi]# modinfo aic7xxx/aic7xxx.ko
filename:       aic7xxx/aic7xxx.ko
description:    Adaptec Aic77XX/78XX SCSI Host Bus Adapter driver
license:        Dual BSD/GPL
version:        6.2.36 96FAE27D3385BBB774E4EDE
parm:           aic7xxx:period delimited, options string.
        verbose                 Enable verbose/diagnostic logging
        allow_memio             Allow device registers to be memory mapped
        debug                   Bitmask of debug values to enable
        no_probe                Toggle EISA/VLB controller probing
        probe_eisa_vl           Toggle EISA/VLB controller probing
        no_reset                Supress initial bus resets
        extended                Enable extended geometry on all controllers
        periodic_otag           Send an ordered tagged transaction
                                periodically to prevent tag starvation.
                                This may be required by some older disk
                                drives or RAID arrays.
        reverse_scan            Sort PCI devices highest Bus/Slot to lowest
        tag_info:<tag_str>      Set per-target tag depth
        global_tag_depth:<int>  Global tag depth for every target
                                on every bus
        dv:<dv_settings>        Set per-controller Domain Validation Setting.
        seltime:<int>           Selection Timeout
                                (0/256ms,1/128ms,2/64ms,3/32ms)

        Sample /etc/modprobe.conf line:
                Toggle EISA/VLB probing
                Set tag depth on Controller 1/Target 1 to 10 tags
                Shorten the selection timeout to 128ms

        options aic7xxx 'aic7xxx=probe_eisa_vl.tag_info:{ { }.{.10} }.seltime:1'
